摘　　要：采用水热方法,用联苯三羧酸配体(H_3btc)和菲咯啉(phen)或2,2′-联吡啶(2,2′-bipy)分别与CoCl_2·6H_2O、PbCl_2和ZnCl_2反应,合成了一个单核配合物[Co(Hbtc)(phen)_2(H_2O)]·3H_2O(1)以及2个一维链状配位聚合物[Pb(μ_3-Hbtc)(2,2′-bipy)]_n(2)和{[Zn_3(μ_2-btc)_2(μ_2-H_2O)(2,2′-bipy)_3(H_2O)_5]·8H_2O}_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,Pna2_1和P1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(Ⅱ)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 P1. 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.
