Two new bimetallic phosphates, namely, Sn2Ge(PO4)2(OH)2 (1) and anhydrous Sn2Mn(PO4)2 (2) have been prepared by a facile hydro/solvothermal method. Compound 1 crystallizes in space group P21/c and features a three‐dimensional (3D) framework which is constructed from one‐dimensional (1D) [Ge(PO4)2(OH)2] infinite chains and the SnO3 trigonal pyramids. Compound 2 crystallizes in space group C2/c and also features a 3D framework which is composed of a two‐dimensional tin phosphates layer in the bc plane and MnO6 octahedra connected with the adjacent layers. Powder X‐ray diffraction (PXRD) patterns, Thermogravimetric analyses (TGA), UV‐Vis‐NIR absorption spectra and IR spectra for both compounds were examined. TGA results show that anhydrous Sn2Mn(PO4)2 has a high thermal stability under 800 °C. Their photoluminescence study indicates that 1 and 2 might be pure inorganics for potential intrinsic green and blue light‐phosphors, respectively.
Two cadmium germanophosphates (GePOs), namely, [CdGe(μ2‐O)(HPO4)2(H2O)2].H2O (1) and anhydrous Cd7Ge(PO4)6 (2) have been prepared by hydro/solvothermal method. Compound 1 crystallizes in a centrosymmetric (CS) space group P‐1 with a 2D layer structure, which is composed of 1D [Cd(HPO4)4(H2O)2]∞ and [Ge(μ2‐O)2(HPO4)4]∞ infinite chains. Compound 2 crystallizes in a centrosymmetric space group R‐3 with a complicated 3D network, which is built from CdO6 octahedra, GeO6 octahedra and PO4 tetrahedra. TGA results showed that the structure of anhydrous Cd7Ge(PO4)6 was stable under 800 °C. The luminescent properties of two compounds were also investigated at room temperature. The color coordinate of 2 (0.2613, 0.2649) is close to that of the balanced white‐light emission (0.333, 0.333), which indicates that compound 2 is a good blue light emitted material at room temperature under UV irradiation exaction, thus anhydrous compound 2 might be a potential candidate for blue light‐emitted material.
Solvothermal reactions of HgI 2 , 4,4Ј-vinylenedipyridine, and HI in alcoholic solution (methanol, ethanol, or pentanol) gave rise to a family of organic-inorganic hybrid complexes, formulated as [C 14 H 16 N 2 ][I 4 ] 2-(1), [C 16 H 20 N 2 ][HgI 4 ] (2), and [C 22 H 32 N 2 ][HgI 4 ] 4 (3). Single-crystal X-ray diffraction reveals that all three compounds are discrete structures, including the inorganic anion [I 4 ] 2or [HgI 4 ] 2and an organic cation, where the resulting organic cations were gener-* Prof. Dr. J.-L.
