摘要 通过水热法合成两个混配的配位聚合物[M(bipy)(Metha)2]n·nH2O(M=Ni,1;Co,2;bipy=4,4′-联吡啶;Metha=甲酸),并对配合物进行了元素分析、红外光谱和X-射线单晶衍射测定。结果表明,2个配合物为单斜晶系,C2/c空间群。配合物1和2具有相似的三维网状结构。配体Metha以2种不同的类型与M2+离子配位,一种是Metha中的2个氧原子作为桥联配位原子,连接着由bipy作为双基配体连接2个不同的金属离子构成的链,另一个Metha中的羧基氧只有1个氧原子与金属离子配位,使配合物构成三维结构。 Two transition metal complexes, [M(bipy)(Metha)2]n.nH20 (M=Ni, 1; Co, 2; bipy=4,4'-bipyridine, Metha= methanoic acid), have been synthesized by hydrothermal synthesis and characterized by elemental analyses, IR spectroscopy, and X-ray single-crystal diffraction etc. The single crystal structures show the two complexes belong to monoclinic system, C2/c space group. Complexes 1 and 2 have similar 3D network structures. Metha have two kinds of different types with ME+ ion, one kind is the two oxygen atoms of the Metha as bridging ligand atoms, connected by chain with bipy, another is the carboxyl oxygen of the Metha with only one oxygen atom with another M2~ ion.
