摘　　要：合成了一个新颖的Co-Cu分子化合物,用元素分析和差热—热重分析方法测定了它的组成,并在Nicolet R_3四园衍射仪上,用MoKa幅射测定了它的单晶结构。晶体属单斜晶系,空间群为P2_1/a,晶胞参数a=12.123(3)(?),b=10.019(3)(?),c=19.287(7)(?),β=105.16(2)°,V=2261(1)(?)~3,Z=4。晶体属分子晶体,在晶胞中两种不同类型的分子共存,一是钴的双水杨醛三乙四胺配合物,其中钴与六齿配体上的两个O原子和四个N原子螯合配位,形成八面体配位中心。另一个是氯化铜分子,通过两个桥式氯原子相连,以二聚形式存在。A new type compound C20H24N4O2Co ?CuCl2 ?H2O has been obtained by the reaction of cobalt bis-salicylidene-triethylenetetraamine with CuCl2. Its component is determined by the results of elemental analyses and thermogravimetric-differential and its crystal structure is determined with a Nicolet R3 diffractometer using MoKa radiation. The crystal belongs to monoclinic, space group is P21/a, a= 12.123(3)A, b= 10.019(3)A, c= 19.287(7)A, β= 105.16(2)°, K=2261(1)A3 and Z = 4. This crystal is a molecular crystal consisting of two types molecules. One is cobalt bis-salicylidene-triethylenetetraamine, the Co atom coordinated with two O atoms and four N atoms of hex-dentate dictating ligand to form a coordination octahedron, the other is a dimer of cupric chloride which locates at a crystallographic symmetry center.
