| 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。 |

| Abstract: Four new cobalt and nickel complexes containing a polypyridine-amine ligand were designed and prepared, namely, [M(L1)](BF4)2 (L1=N,N,N',N'-tetrakis(2-pyridylmethyl)ethane-1,2-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. |
