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 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.

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.

Thermal analysis shows that the compound is thermally stable up to about 350 °C. The solid state UV-vis-NIR diffuse reflectance spectrum indicates that Bi 2 (IO 3 )(IO 6 ) is a semiconductor with a band gap of 2.76 eV.

Exploring optoelectronic functional materials has been of growing interest, due to their potential applications in information and energy storage. Pressure, as a direct way of modulating the localized groups of materials, has the potential to induce significant changes in optoelectronic properties. Herein, we adopt the pressure method to synergistically modulate the configuration of dual functional groups in CsMoO3(IO3) (i.e., lone-pair electrons [IO3] and second-order Jahn–Teller [MoO6] groups). Under pressure, CsMoO3(IO3) undergoes an isostructural phase transition, resulting in multiple optoelectronic changes of the “colorless-to-brown” piezochromism, the second harmonic generation “on-to-off” transformation, and the enhancement of the photocurrent switching ratio (× ∼10 times). First-principles calculations are also employed to explain the structure–property relationship. This work will shed light on further advancements in functional materials with multiple optoelectronic properties in extreme environments.

Two new alkali–metal bismuth iodates KBi(IO3)3(OH) (1) and NaBi(IO3)4 (2) have been synthesized by a hydrothermal method via tuning of alkali–metal ions. Compound 1 crystallizes in the space group P and features a [Bi(IO3)3(OH)]n chain with eight-membered Bi–O–I–O–Bi–O–I–O rings. The [Bi(IO3)3(OH)]n chain consists of paddlewheel-like dimeric Bi2(OH)2(IO3)4 units linked by IO3 pairs. Compound 2 in the polar space group Cc features a [Bi(IO3)4]− double layer with Bi4I4 eight-membered rings (8-MRs). NaBi(IO3)4 exhibits a strong second harmonic generation (SHG) response of ∼5.0 × KDP (KH2PO4) and a wide transmittance window (0.4–12 μm), and structure analyses and theoretical calculations reveal that polarization results mainly from the proper alignment of the IO3 groups. The calculated electronic structure based on the DFT method indicates that the BiOn and IO3 groups dominate their optical properties.

An alkali metal gallium iodate, Cs3[Ga2O(I3O9)(IO3)4(HIO3)] (CGIO), was synthesized by the traditional hydrothermal method. Interestingly, CGIO revealed a novel I3O93− fundamental building block (FBB) constituted by two IO3 tetrahedrons and one IO5 polyhedron through sharing O atoms. The new I3O93− trimer forms a 0D [Ga2O(I3O9)(IO3)4(HIO3)]3− anion cluster together with the [Ga2O11]16− dimer and isolated IO3− units. The UV-vis-NIR diffuse reflectance spectrum of CGIO shows a wide bandgap of 4.05 eV, and the thermal stability could reach above 400 °C. First-principles calculations explicated that the optical properties of CGIO mainly originated from the iodate anion units with a calculated birefringence of 0.04 at 1064 nm.

Nonlinear optical (NLO) crystals are indispensable for the solid-state lasers for their ability to expand wavelength spectral to the regions where the directing lasing is difficult or even impossible, yet the rational design of a high-performance NLO crystal remains a great challenge owing to the severe structural and properties’ requirements. Herein, a new noncentrosymmetric (NCS) and polar gallium iodate, LiGa(IO 3 ) 4 , with a novel 2D anionic layer, is successfully designed and synthesized by the aliovalent substitution strategy based on classic α-LiIO 3 . The 2D [Ga(IO 3 ) 4 ] ∞ − layer in LiGa(IO 3 ) 4 is built from the GaO 6 octahedra and highly polarizable units IO 3 . Compared with its parent compound, the partial replacement of A-site Li + cation with main group Ga 3+ cation facilitates LiGa(IO 3 ) 4 to possess excellent NLO properties, including the large second-harmonic generation (SHG) response (14 × KH 2 PO 4 (KDP) @ 1064 nm), wide bandgap (4.25 eV), large birefringence (0.23 @ 1064 nm), and wide optical transparency from UV to mid-IR. These reveal that LiGa(IO 3 ) 4 will be a promising NLO crystal.
