摘　　要：设计合成了4个新的钴、镍多齿吡啶-胺配合物,[M(L1)](BF4)2(L1=N,N,N′,N′-四(2-吡啶甲基)-1,2-乙二胺;C1,M=Co;C2,M=Ni)和[M(L2)](BF4)n(L2=N,N,N′,N′-四(2-吡啶甲基)-1,3-丙二胺;C3,M=Co,n=3;C4,M=Ni,n=2)。利用红外光谱、元素分析和X-射线单晶衍射方法对这些配合物的组成及结构进行了分析和表征。这4个配合物的单晶结构均属于单斜晶系,空间群有所不同(C1为Cc空间群,C2为P21/n空间群,C3为C2/c空间群,C4为P21/c空间群),并且4个配合物具有不同的三维堆积结构。Four new cobalt and nickel complexes containing a polypyridine-amine ligand were designed and prepared, namely, [M（L1）]（BF4）2 （Ll=N,N,N＇,N＇-tetrakis（2-pyridylmethyl）ethane-l,2-diamine; C1, M=Co; C2, M= Ni） and [M（L2）]（BF4）n （L2=N,N,N＇,N＇-tetrakis（2-pyridylmethyl）propane-1,3-diamine; C3, M=Co, n=3; C4, M=Ni, n =2）. These complexes were characterized by infrared spectroscopy （IR） and element analysis （EA）. The structures of the complexes were determined by X-ray single crystal diffraction. The four complexes all belong to the monoclinic crystal system but with different space groups （C1, Cc; C2, P21/n; C3, C2/c; C4, P21/c）. Different three-dimensional packing structures were found for these complexes.
