摘　　要：采用水热方法,用联苯三羧酸配体(H3dppa)和4,4′-联吡啶(4,4′-bipy)分别与CuCl_2·2H_2O和MnCl_2·4H_2O反应,合成了一个具有零维双核铜结构的配合物[Cu_2(Hdppa)_2(4,4′-bipy)(H_2O)_4]·4,4′-bipy·6H_2O(1)和一个基于双螺旋链单元的三维配位聚合物{[Mn_3(μ_5-dppa)_2(4,4′-bipy)(H_2O)_2]·4H_2O}_n(2),并对其结构和磁性质进行了研究。结构分析结果表明2个配合物分别属于三斜和单斜晶系,P1和C2/c空间群。配合物1具有零维双核铜结构,而且这些双核铜单元通过O-H…O/N氢键作用进一步形成了三维超分子框架。而配合物2中存在一个双螺旋锰链单元,这些锰链单元又通过配体进一步连接成了三维结构。研究表明,配合物2中相邻锰离子间存在反铁磁相互作用。Zero dimensional dinuclear copper （Ⅱ） coordination compound and 3D manganese （Ⅱ） coordination polymer, namely [Cu2（Hdppa）2（4,4′-bipy）（H2O）4]·4,4′-bipy·6H2O（1） and {[Mn3（ μ5-dppa）2（4,4′-bipy）（H2O）2]·4H2O}n（2）, have been constructed hydrothermally using H3 dppa, 4,4′-bipy（H3dppa=5-（3,4-dicarboxylphenyl）picolinic acid,4,4′-bipy=4,4′-bipyridine）, and copper or manganese chlorides. Single-crystal X-ray diffraction analyses revealed that two compounds crystallize in the triclinic or monoclinic system, space group P1 or C2/c. In compound 1, one 4,4′-bipy ligand bridges neighboring Cu（Ⅱ） ions to form a discrete dinuclear copper（Ⅱ） structure. These Cu2 units are assembled to a 3 D supramolecular framework through O-H … O/N hydrogen bond. In compound 2, neighboring Mn（Ⅱ） ions are bridged by the carboxylate groups of μ5-dppa3- ligands, producing a double-helix Mn（Ⅱ） chain subunit.The adjacent double-helix chains subunits are further linked by the dppa3- blocks and 4,4′-bipy ligands into a 3D framework. Magnetic studies for compound 2 demonstrate an antiferromagnetic coupling between the adjacent Mn（Ⅱ） centers.
