摘　　要：采用水热方法,用2种联苯三羧酸配体biphenyl-2,5,3′-tricarboxylate acid(H_3bptc)和2-(4-carboxypyridin-3-yl)terephalic acid(H_3cptc)以及菲咯啉(phen)或2,2′-联吡啶(2,2′-bipy)分别与Ni Cl_2·6H_2O和Mn Cl_2·4H_2O反应,合成了一个具有零维四核镍结构的配合物[Ni_2(μ_3-Hbptc)(Hbptc)(phen)_3(H_2O)]_2·4H_2O(1)和一个基于三核锰单元的一维链状配位聚合物{[Mn_3(μ_4-cptc)_2(2,2′-bipy)_2(H_2O)_4]·2H_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个配合物均属于三斜晶系,P1空间群。配合物1具有零维四核镍结构,而且这些四核镍单元通过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中存在一个中心对称的三核锰单元,这些三核锰单元又通过配体进一步连接成了一维链。研究表明,配合物1和2中相邻金属离子间存在反铁磁相互作用。A 0D tetranuclear nickel(Ⅱ)coordination compound and a 1D manganese(Ⅱ)coordination polymer,namely[Ni2(μ3-Hbptc)(Hbptc)(phen)3(H2O)]2·4H2O(1)and{[Mn3(μ4-cptc)2(2,2′-bipy)2(H2O)4]·2H2O}n(2),have been constr-ucted hydrothermally using H3bptc(H3bptc=biphenyl-2,5,3′-tricarboxylate acid),H3cptc(H3cptc=2-(4-carboxypyri-din-3-yl)terephalic acid),phen(phen=1,10-phenanthroline)or 2,2′-bipy(2,2′-bipy=2,2′-bipyridine),and nickel or manganese chlorides.Single-crystal X-ray diffraction analyses revealed that both compounds crystallize in the triclinic system,space group P1.In compound 1,twoμ3-Hbptc2-ligands bridge alternately neighboring Ni(Ⅱ)ions to form a discrete tetranuclear nickel(Ⅱ)structure.These Ni4 units are assembled to a 3D supramolecular framework through O-H…O hydrogen bond.In compound 2,three neighboring Mn(Ⅱ)ions are bridged by four differentμ4-cptc3-ligands,giving rise to a centrosymmetric trinuclear Mn(Ⅱ)subunit.The adjacent Mn3 subunits are further linked by the cptc3-blocks into a 1D chain.Magnetic studies for compounds 1 and 2 demonstrate an antiferro-magnetic coupling between the adjacent metal centers.CCDC:1588394,1;1588395,2.
