The crystal belongs to hexagonal, space group P63cm with a = 11.699（I ）, c = 5.8279（9） A°, Mr = 276.26, V = 690.8（1 ）A°^ 3, Z = 6, D, = 3.985 g/cm^3, F（000） = 756, μ = 9.913 mm^-1, S = 1.004, R = 0.0719 and wR = 0.2204. The title compound is the first example containing S anion in the ternary alkali metal chalcogenide halides family M3QX （M = alkali metal, Q = chalcogenide, X - halide）, which crystallizes in the hexagonal anti-perovskite structure type.展开更多
Two-dimensional 4,4-bipyridyllead halides, PbI_2(4,4′-bpy)(1) and PbBr_2(4,4′-bpy)(2), were synthesized. The structures were determined by means of X-ray single crystal diffraction.

The structures were determined by means of X-ray single crystal diffraction. The structure shows a distorted octahedral configuration with six-coordinated central lead atoms. In crystals 1 and 2, the molecules are packed in a two-dimensional network structure through bridging halide atoms and 4,4′-bipyridine ligands between the adjacent lead atoms.展开更多
The title compound Cu 2Cl 2phen (phen=1,10 phenanthroline, C 12 H 8N 2) 1 was synthesized from CuCl 2·2H 2O, CuCl and phen by hydrothermal method and its structure was determined by single crystal X r...The title compound Cu 2Cl 2phen (phen=1,10 phenanthroline, C 12 H 8N 2) 1 was synthesized from CuCl 2·2H 2O, CuCl and phen by hydrothermal method and its structure was determined by single crystal X ray analysis. With phen, CuCl forms one dimensional chains, which comprise two zigzag chains based on fused Cu X units and connected via covalent bonds. The compound contains two crystallographically unique monovalent copper ions, Cu(1) and Cu(2). The Cu(1) atom in the tetrahedral site, is coordinated to two bridging Cl - and two N atoms in phen. The Cu(2) atom with a slightly distorted triangular planar geometry, is coordinated to three Cl -. The compound 1 was crystallized in monoclinic, space group P 2 1/ n with a = 0.37338(4) , b =1.9510(2), c =1.68008(19) nm, β =95.605(3)°, R =0.0458, and was characterized by elemental analysis, IR spectrum and TGA analysis.展开更多
