摘要
以均苯三酸为有机桥联配体,在水热条件下合成了两个新颖Co(Ⅱ)/Cd(Ⅱ)配位聚合物:{[Co3(μ3-OH)(μ2-H2O)2(H2O)5(BTC)2]·6H2O}n(1),[Cd(H2O)2(HBTC)]n(2)(H3BTC=均苯三酸),并用元素分析、红外光谱、热重分析、X-粉末衍射、X-射线单晶衍射对配合物进行了表征.X-射线单晶衍射结果表明:配位聚合物1中含有一个三核的钴氧簇,均苯三酸作为一个桥联配体连接相邻的钴氧簇形成一个一维的链状结构.配位聚合物2是一个二维的(63)层状结构.另外,研究了配位聚合物1和2的热稳定性能.
Two novel MCPs：{[Co3（μ3-OH）（μ2-H2O）2（H2O）5（BTC）2]·6H2O}n（1）,[Cd（H2O）2（HBTC）]n（2）（H3BTC=1,3,5-benzenetricarboxylic acid）was prepared and characterized by single crystal X-ray diffraction,powder XRD,FTIR,TGA and elemental analysis techniques.The single crystal X-ray diffraction reveals that MCP 1consist of 1Dinfinite Zigzag chains which was constructed by trinuclear Cobalt cluster and BTC3-ligand.Meanwhile,MCP 2shows a two dimensional sheet structure formed by Cd（II）metal centers and HBTC2-ligands showing honeycomb caves.In addition,the stability of 1and 2were investigated.
