Three new iodates SrTi(IO3)6·2H2O, (H3O)2Ti(IO3)6, and SrSn(IO3)6 have been synthesized via a facile hydrothermal method. The three compounds have zero-dimensional crystal structures composed of one [MO6]8− (M = Ti, Sn) octahedron connected with six [IO3]− trigonal pyramids. However, the particular coordination of Sr2+ cations results in distinct arrangements of lone pair electrons in an [IO3]− trigonal pyramid, which leads to large birefringences. More importantly, this work enriches the species crystal chemistry for [M(IO3)6]2− (M = Ti, Sn) clusters-containing iodates.

A new d10 transition-metal iodate fluoride, namely, Cd3(IO3)(IO4)F2·0.1CdO, was successfully designed and synthesized via the mid-infrared hydrothermal method. It crystallizes in the polar space group R3m and features the coexistence of the [IO3]− and [IO4]3– groups. Cd3(IO3)(IO4)F2·0.1CdO has a strong second-harmonic-generation response of about 3.0 times that of KDP(KH2PO4), large birefringence (0.133 at 546.1 nm), and a wide energy band gap (4.00 eV). In addition, the power laser damage threshold (LDT) measurement indicated that it possesses a high LDT of 84.29 MW/cm2, which is about 30 times that of AgGaS2. These superior properties showed that Cd3(IO3)(IO4)F2·0.1CdO may be an excellent nonlinear-optical crystal for visible and mid-infrared application.

The reactive oxygen species (ROS) level as an hopeful strategy for cancer therapy, mainly including photodynamic therapy (PDT) and chemodynamic therapy (CDT). It is well known both PDT and CDT greatly rely on oxygen reliance, inherent flaws of traditional photosensitizers, and lowly selectivity between normal cells and tumor cells. Herein, we reported Zr(IO 3)4 nanoparticles as a biocompatible nanozyme with effective ROS supply by Feton-like reaction and Brady reaction. The Zr(IO 3 ) 4 exhibiting a remarkable selectivity between normal cells and tumor cells. Importantly, the Zr(IO 3 ) 4 , H 2 O 2 -responsive and GSH-depleted nanozymes, were explored for tumor therapy. Nanozyme is highly important from the deep cancer therapy point of view. In this work, we prepared Zr(IO 3 ) 4 by a simple method. The obtained Zr(IO 3 ) 4 samples showed obvious performance in treatment of cancer. It was confirmed by the electron spin resonance (ESR) as well as the fluorescence probe results of Zr(IO 3 ) 4 that the treatment of cancer due to the reactive oxygen species.

Nonlinear optical (NLO) crystals assume an irreplaceable role in the development of laser science and technologies, yet the reasonable design of a high-performance NLO crystal remains difficult owing to the unpredictability of inorganic structures. In this research, we report the fourth polymorph of KMoO3(IO3), i.e., δ-KMoO3(IO3), to understand the effect of different packing patterns of basic building units on structures and properties. Among four polymorphs of KMoO3(IO3), the different stacking patterns of Λ-shaped cis-MoO4(IO3)2 units result in α- and β-KMoO3(IO3) featuring nonpolar layered structures, whereas γ- and δ-KMoO3(IO3) display polar frameworks. Theoretical calculations and structure analysis reveal that IO3 units can be regarded as the main source of its polarization in δ-KMoO3(IO3). Further property measurements show that δ-KMoO3(IO3) exhibits a large second-harmonic generation response (6.6 × KDP), a wide band gap (3.34 eV), and a broad mid-infrared transparency region (∼10 μm), which demonstrates that adjusting the arrangement of the Λ-shaped basic building units is an effective approach for rationally designing NLO crystals.

The efficient photogenerated carriers separation is the key factor in enhancing the activity of photocatalysts to solve environmental pollution problems. The internal polarized electric fields in polar materials most likely provide a more direct and stronger driving force for photogenerated carriers separation. Here, we investigate polar ε -Cd(IO 3 ) 2 (CIO) with two different morphologies as an efficient photocatalyst for the photodegradation of antibiotics and dyes. According to the theoretical calculation of the ratios of m h */ m e * along three different crystal axis directions, the photogenerated carrier separation efficiency along the c -axis direction is the largest, which matches the direction of the polarized electric field in the crystal. The internal polarized electric field promotes the separation of photogenerated carriers, leading to a high transfer efficiency of the catalyst. Moreover, photodegradation experiments demonstrate that the photocatalytic activity of CIO-1 is approximately 3 times that of TiO 2 P25. This study provides some insights that might aid the development of polar photocatalysts with superior performance.

Birefringent crystals are extensively utilized across diverse optical applications due to their unique property of splitting incident light into dual refracted rays, thereby modulating and controlling light polarization. The pursuit of promoting the birefringence of such crystals to facilitate device miniaturization has recently emerged as a prominent area of focus. In this investigation, we introduce two molybdenyl iodates, namely, C(NH2)3MoO3(IO3) and Rb2MoO2(I2O6)(IO3)2, conceived through a “cation–anion synergetic interaction” strategy. Each compound exhibits a one-dimensional chain structure. Despite processing similar wide band gaps (3.33 and 3.22 eV), these materials display a variance in their birefringence (Δn = 0.426 and 0.261 @546 nm). Notably, C(NH2)3MoO3(IO3) showcases the highest birefringence among all hitherto reported molybdenyl iodates, signifying its potential as a high-performance birefringent crystal. Theoretical analyses indicate that the C(NH2)3+ cation, acting as a birefringence-active unit, significantly bolsters the birefringence of molybdate iodates. Moreover, the presence of extensive hydrogen-bonding interactions between C(NH2)3+ cations and iodates influences the orientation of the highly anisotropic iodates, thereby further enhancing the birefringence of C(NH2)3MoO3(IO3). This research paves the way for the future exploration of organic–inorganic hybrid molybdenyl iodates exhibiting exceptional optical performance.

The ever-increasing need for energy-dense batteries with high safety is fuelling global research and innovations in new redox chemistry and device design. Here we show an aqueous battery employing highly concentrated hetero-halogen electrolytes that contain I − and Br - , resulting in a multielectron transfer process of I − /IO 3 − . The intermediate bromide species IBr and Br 2 , generated during the electrochemical process, enhances the reaction kinetics and alleviates the potential gap between oxidation and reduction. When using a 6 M I − electrolyte to achieve over 30 M electron transfers, the I − /IO 3 − cathode displayed a high specific capacity of over 840 Ah l catholyte −1 . A battery with Cd/Cd 2+ as the anode demonstrated a high energy density of over 1,200 Wh l catholyte −1 . Even at an exceptionally high current density of 120 mA cm −2 , an energy efficiency of 72% was obtained. Our work demonstrates that safe aqueous batteries with high energy density are possible, offering a development option for grid-scale energy storage and even electric vehicles.

Exploring feasible tactics to induce the formation of non-centrosymmetric (NCS) structures, especially from centrosymmetric (CS) structures, is essential for the development of nonlinear optical crystals with more potential. An NCS alkali metal-containing molybdenum iodate hydrate, namely, NaMoO3(IO3)(H2O), was designed based on the CS matrix NaMoO3(IO3) via introducing a water molecule into the structure. The introduction of one crystalline water molecule results in the rearrangement of Λ-shaped cis-[MoO4(IO3)2] units, and the proper array of the cis-[MoO4(IO3)2] units in NaMoO3(IO3)(H2O) results in its strong SHG response of 4.6 × KH2PO4. In addition, NaMoO3(IO3)(H2O) exhibits a wider optical bandgap of 3.44 eV and a larger birefringence of 0.231 than its matrix. Furthermore, the framework of NaMoO3(IO3)(H2O) is highly similar to that of α-KMoO3(IO3), with water molecules assisting Na+ cations in occupying the position of K+. However, due to the extra hydrogen bond of water molecules, the [MoO3(IO3)]∞ layers in NaMoO3(IO3)(H2O) retain a parallel-stacking arrangement, different from the antiparallel arrangement of layers in α-KMoO3(IO3) with a centric structure. This study confirms the feasibility of applying a water molecule to adjust the orientation of basic building block units to assemble an NCS structure based on CS crystals.

Scintillators, which can emit visible photons under γ- or X-ray excitation, are widely used in radiation detection. Traditional inorganic scintillators usually have some drawbacks, such as hygroscopicity or a high synthesis temperature, and most of them are poisonous. Hence, we report the synthesis of metal iodate scintillators (Eu(IO3)3 and Tb(IO3)3) by a facile hydrothermal reaction that exhibit good radioluminescence (RL) intensity. To further increase the RL intensities, we prepared Eu(IO3)3:xSm and Tb(IO3)3:xGd with stronger RL intensities and higher sensitivities than BaF2 and PbWO4 powders when x = 3%. Furthermore, we obtained scintillating films consisting of Eu(IO3)3:3%Sm and Tb(IO3)3:3%Gd for X-ray imaging. Our Eu(IO3)3:3%Sm and Tb(IO3)3:3%Gd films revealed excellent luminescence under high-energy X-ray excitation and spatial resolutions down to 9 lp mm−1 and 8 lp mm−1, respectively. Thus, these films can be regarded as candidate materials for X-ray imaging.

Low-dimensional quantum magnets exhibit exotic quantum
phenomena
such as short-range order, spin gap, and spin liquid, with potential
applications in spintronics and quantum technologies. These quantum
phenomena are usually observed in magnetic systems with strong spin
exchange mediated by monatomic ions like O 2– , particularly
with small quantum spins S . Herein, we report that
IO 3 – polyatomic ions mediate efficient
spin exchange, resulting in the rarely observed short-range magnetic
order at 13.8 K in a novel two-dimensional S = 5/2
iodate-fluoride, LiFe(IO 3 ) 2 F 2 , with
a honeycomb lattice. This is also supported by a negative Weiss temperature
of −25 K and DFT calculations. The compound further undergoes
a three-dimensional antiferromagnetic (AFM) long-range order at 9.9
K following the short-range ordering. In addition, the magnetization
measured at 2 K reveals a spin-flop transition around 4.4 T. These
findings demonstrate that the IO 3 – bridge
provides a new strategy to chemically construct novel low-dimensional
magnetic systems, offering a platform to explore exotic quantum phenomena
and enabling potential applications in quantum computing and spin-based
technologies.

Introducing F– anions or substituting F– anions with IO3– groups has been proven to be ideal strategies for designing novel noncentrosymmetric (NCS) and polar materials, yet systematic investigation into the effect of F– anions or the substitution of IO3– for F– anions on structures and properties remains rarely explored. Herein, two new gallium iodates, NaGa(IO3)2F2 (1) and NaGa(IO3)4 (2), were successfully designed and synthesized based on NaGa(IO3)3F by introducing more F– anions and replacing F– anions with IO3 groups, respectively. Structurally, in compound 1, the adjacent [GaF3(IO3)3]3– polyanions are connected in an antiparallel manner, resulting in a complete cancellation of local polarity. While in compound 2, all IO3 groups in 2D [Ga(IO3)4]∞– layers are aligned, leading to large macroscopic polarization. Additionally, chemical substitution also results in a qualitative improvement in the functional properties of compound 2. It possesses strong SHG response (12 × KDP @1064 nm) and broad optical transparency, coupled with large birefringence (0.21 @1064 nm), showcasing its promise as a promising nonlinear optical (NLO) crystal. The effects of chemical substitution between F– anions and IO3– groups on the structures and properties are discussed in detail.

A new iodate K 2 HGa(IO 3 ) 6 (CCDC: 2485176) has been synthesized via the facile hydrothermal method in the K 2 O-Ga 2 O 3 -I 2 O 5 system. The crystal structure of K 2 HGa(IO 3 ) 6 features a zero-dimensional [Ga(IO 3 ) 6 ][ 3 ] - structural building units (SBUs) with the cavities filled by the K, H cations to keep the charge balance. UV-Vis-NIR diffuse reflectance and IR spectrum were used to characterize the optical properties. TG-DSC shows that K 2 HGa(IO 3 ) 6 was no weight loss before 440°C.
