Two new tetranuclear cluster-based compounds, namely [Cd 2 (L1)(H 2 O)(DMA)] n ( 1 ) and [Cd 2 Ba 2 (L2)(H 2 O) 6 (DMA)] n ( 2 ) [H 4 L1 = 3-(3',5'-dicarboxylphenoxy) phthalic acid, H 4 L2 = 6-(3',4'-dicarboxyl-phenoxy) isophthalic acid, DMA = N,N' -dimethylacetamide], were successfully synthesized under solvothermal conditions and structurally characterized by single-crystal X-ray diffraction analyses. Compound 1 features a two-dimensional (2D) layered framework with tetranuclear [Cd 4 (COO) 6 ] clusters as building subunits, and can be simplified into a binodal (3, 6)-connected kgd topological network with the schläfli symbol of {4 3 } 2 {4 6 ;6 6 ;8 3 }, and compound 2 features a three-dimensional (3D) complicated framework based on heterometallic tetranulear [Cd 2 Ba 2 (COO) 8 ] cluster subunits, and can be simplified into a binodal (3, 6)-connected topological network. In addition, compounds 1 and 2 not only have high thermal stabilities but also show strong luminescent emissions at room temperature.

By using mixed rigid and flexible organic ligands, three Keggin based compounds, [Ag6(tbz)4(bmz)2(H3PW12O40)]·4H2O (1), [Ag(H2bdpm)2(H2PMo12O40)]·7.5H2O (2), and [Ag4(tbz)2(H2bdpm)2(HPMo12O40)]·2H2O (3) (Htbz = thiabendazole, Hbmz = benzimidazole, H2bdpm = 1,1′-bis(3,5-dimethyl-1H-pyrazolate)methane), were hydrothermally synthesized and structurally characterized. Through adopting rigid Htbz ligands, compound 1 with hexa-nuclear AgI clusters has been obtained. These hexa-nuclear clusters are linked by Keggin anions alternately to form a one dimensional (1D) chain. In compound 2, the organic moiety is the flexible H2bdpm ligand. The Keggin anions are fused by [Ag(H2bdpm)2]+ subunits to form a 1D chain. In compound 3, the rigid Htbz and the flexible H2bdpm cooperate to modify the anions. Two tbz and two H2bdpm are fused by four AgI ions to construct a tetra-nuclear AgI cycle. The anions connect these cycles through Ag–O bonds alternately to form a 1D chain. Adjacent chains arrange parallel to build a 2D layer. The chains in the adjacent layers are vertically packed and linked by Ag–O bonds to construct a 3D framework. The electrochemical and photocatalytic properties of the title compounds have been studied. Furthermore, we have also studied the Hg2+ recognition properties in a suspension of compounds 1 and 3.

A convenient synthetic route has been developed for preparing the novel rigid 4,5-(PR2)2–2,7,9,9-tetramethylacridane-based pincer ligands (acri-RPNP; R = iPr and Ph), and the first rare-earth (Ln = Y, Lu) alkyl complexes bearing the acri-RPNP ligands were synthesized by a salt metathesis reaction (for the isopropyl-substituent acri-iPrPNP complexes, 1-Ln) or direct alkylation (for the phenyl-substituent acri-PhPNP complexes, 2-Ln). For both 1-Ln and 2-Ln, the NMR spectroscopy and X-ray diffraction study confirmed the successful coordination of the acri-RPNP ligand to the central metal ion in a tridentate manner via the two phosphine and the nitrogen donors. In contrast to 1-Ln that are solvent-free complexes, the metal centers in 2-Ln are each coordinated with one tetrahydrofuran molecule. Upon activation by [Ph3C][B(C6F5)4], 1-Y and 2-Lu could catalyze the living polymerization of isoprene and β-myrcene with high catalytic activity and high cis-1,4-selectivity (up to 92.3% for isoprene and 98.5% for β-myrcene). Moreover, the 1-Y/[Ph3C][B(C6F5)4] catalytic system also could promote the polymerization of butadiene and its copolymerization with isoprene to produce copolymers with high cis-1,4-selectivity and narrow polydispersity.

Uranyl coordination polymers have caught more and more attention due to their rich topological structures and potential practical applications in nuclear waste processing and management. In this work, four novel uranyl coordination polymers have been successfully synthesized by the utilization of a semirigid ligand and uranyl nitrate under hydrothermal reactions through the introducing of different kinds of auxiliary ligands (NaCl, oxalate acid, succinic acid). Therein, the powder X-ray diffraction, Infrared spectroscopy and luminescence properties of compounds 3 and 4 are investigated.
