Structure analysis shows that the inorganic anion chain consists of distorted PbI6 octahedra, which shares the same faces with adjacent PbI6 units to form one-dimensional infinite chains along the c-axis. Anion chains are surrounded by protonated （DBU-H）^＋ cations. Anion chains and cations are in combination with each other by static attracting forces in the crystal to form so-called organic-inorganic hybrid structure. According to the crystal structure data, quantum chemical calculation with DFT at B3LYP level was used to reveal the electronic structure of title compound.     

Synthesis,Structure and Luminescent Properties of [Zn（btzb）2Cl2]·2H2O [btzb = 1,2-Bis（5-tetrazolyl）benzene]

The title compound [Zn（btzb）2Cl2]·2H2O （1·2H2O, btzb = 1,2-bis（5-tetrazolyl）ben- zene） was synthesized in situ by the [2＋3] cycloaddition reaction of phthalonitrile with NaN3 in water in the presence of ZnCl2 under refluxing conditions. 1·2H2O crystallizes in the monoclinic system, space group P2 1/c with a = 9.0119（18）, b = 7.5566（15）, c = 18.076（5）A, β= 114.67（2）°, V= 1118.6（4）A^3, Z = 2, Dc = 1.784 g/cm^3, T= 223（2） K, C16H16N16O2Cl2Zn, Mr = 600.74, F（000） = 608, μ（MoKα） = 1.393 mm^-1, S = 1.081, R = 0.0306 and wR = 0.0669 for 1896 observed reflections with I 〉 2σ（I）. The Zn^2＋ ion of 1 is coordinated by four N atoms from two btzb ligands and two Cl atoms, forming a distorted octahedral coordination geometry. A number of intermolecular hydrogen bon- ding interactions between molecules 1 and/or the solvated water molecules result in a 3D hydrogen-bonded structure. The luminescent property of 1·2H2O was also investigated.     

铋(Ⅲ)配合物Bi(1,10-phen)[S2CN(CH3)2]2(NO3),

Three bismuth（Ⅲ） complexes Bi（1,10-phen）[S2CN（CH3）2]2（NO3） （1）, {Bi（S2COCH3）[S2CNC6Hs（CH3）]2}2 （2） and [Bi（S2CNBu2）2（CH3OH）（NO3）]∞ （3） were synthesized and characterized by elemental analysis and IR spectra. Their crystal structures were determined by X-ray single crystal diffraction analysis. Studies show that complex 1 has a monomeric structure with the central bismuth atom eight-coordinated in a capped distorted pentagonal bipyramidal geometry. The complex 2 takes centrosymmetric dimeric structure and the bismuth atoms are seven-coordinated in distorted pentagonal bipyramidal geometry.In complex 3, the bismuth atoms are seven-coordinated in distorted pentagonal bipyramidal geometry by bridging nitrate O atoms and the resulting structure is onedimensional infinite chain polymer.
