硫属化合物[Co(dien)][Sn_2S_6](dien=diethylenetriamine)的溶剂热合成及其晶体结构

Solvothermal Synthesis and Crystal Structure of [Co(dien)][Sn_2S_6](dien=diethylenetriamine)

在400K温度下,通过溶剂热合成方法,以Co(CH3COO)24H2O,Sn粉,S粉为原料,按化学反应计量比混合,二乙烯三胺和水为溶剂反应合成了一个新的硫属化合物[Co(dien)2][Sn2S6].通过元素分析和X-射线单晶衍射仪对此化合物结构进行表征,化合物属三斜晶系,空间群为P-1.该化合物包含四面体形状的[Sn2S6]4-阴离子和过渡金属配合物阳离子[Co(dien)2]2+.这两种结构单元通过氢键相连形成三维网状结构.

A new transition metal selenidoantimonates, [Co（dien）][Sn2Ss] （dien = diethylenetriamine）, have been synthesized by solvothermal reacting of Co（CH3COO）2.4H20, Sn and S in a stoichiometric ratio in ethanolamine solution at 400 K. The structure was characterized by elemental analysis and single-crystal X-ray diffraction. The compound crystallizes in the triclinic space group P-1. The structure consists of tetrahedral [Sn2S6]^2-anion and transition metal complex [Co（dien）2]^2＋ cation. These three types of units are interlinked via various hydrogen-bonding interactions to from a three-dimensional （3D） network.
