摘要

采用水热方法,用联苯三羧酸配体(H3btc)和菲咯啉(phen)或2,2'-联吡啶(2,2'-bipy)分别与CoCl2·6H2O、PbCl2和ZnCl2反应,合成了一个单核配合物[Co(Hbtc)(phen)2(H2O)]· 3H2O(1)以及2个一维链状配位聚合物[Pb(μ3-Hbtc)(2,2'-bipy)]n(2)和{[Zn3(μ2-btc)2(μ2-H2O)(2,2'-bipy)3(H2O)5]·8H2O}n(3),并对其结构和荧光性质进行了研究.结构分析结果表明3个配合物分别属于正交和三斜晶系,Pna21和P(1)空间群.配合物1具有零维单核结构,而且这些单核钴单元通过O-H…O氢键作用进一步形成了三维超分子框架.而配合物2和3具有基于双核单元的一维链结构.研究表明,配合物2和3在室温下能发出蓝色荧光.%Zero-dimensional mononuclear cobalt(H) complex,1D lead(Ⅱ) and 1D zinc(Ⅱ) coordination polymers,namely [Co(Hbtc)(phen)2(H2O)]· 3H2O (1),[Pb(μ3-Hbtc)(2,2'-bipy)]n (2) and {[Zn3(μ2-btc)2(μ2-H2O)(2,2'-bipy)3(H2O)5] ·8H2O}n (3),have been constructed hydrothermally using H3btc (H3btc=biphenyl-2,4,4'-tricarboxylic acid),phen (phen=1,10-phenanthroline),2,2'-bipy (2,2'-bipy=2,2'-bipyridine),and cobalt,lead or zinc chlorides.Singlecrystal X-ray diffraction analyses revealed that three complexes crystallize in the orthorhombic or triclinic systems,space groups Pna21 or P(1).Complex 1 has a discrete monomeric structure,which is assembled to a 3D supramolecular framework through O-H…O hydrogen bond.Complexes 2 and 3 show a 1D chain based on binuclear units.Luminescent properties of all complexes have been studied.CCDC:1835223,1;1835224,2;1835225,3.
