摘　　要：采用水热方法,选用刚性线型三羧酸配体(H3L)和2,2′-联吡啶(2,2′-bipy)与NiCl2·6H2O分别在120和160 ℃温度下反应,得到了一个具有零维双核镍结构的配合物[Ni2(μ-HL)2(2,2′-bipy)2(H2O)4]·6H2O (1)和一个一维链状配位聚合物{[Ni(μ-HL)(2,2′-bipy)(H2O)2]·H2O}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具有零维双核镍结构,而且这些双核镍单元通过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具有一维链结构。2个配合物的结构差异可能是由于水热反应温度不同造成的。研究表明,配合物2中相邻镍离子间存在反铁磁相互作用。Zero dimensional dinuclear nickel(Ⅱ) coordination compound and 1D chain nickel(Ⅱ) coordination polymer, namely [Ni2(μ-HL)2(2,2′-bipy)2(H2O)4]·6H2O (1) and {[Ni(μ-HL)(2,2′-bipy)(H2O)2]·H2O}n (2), have been constructed hydrothermally using 2,5-di(4-carboxylphenyl)nicotinic acid (H3L), 2,2′-bipyridine (2,2′-bipy), and nickel chloride at 120 or 160 ℃, respectively. Single-crystal X-ray diffraction analyses revealed that both complexes crystallize in the triclinic system, space group P1. Complex 1 discloses a discrete dimer structure, which is assembled to a 3D supramolecular framework through O-H…O/N hydrogen bond. Complex 2 has a chain structure. Structural differences between compounds 1 and 2 may be attributed to the different hydrothermal reaction temperature. Magnetic studies for complex 2 demonstrate an antiferromagnetic coupling between the adjacent Ni(Ⅱ) centers. 2.
