摘要 硝酸镍与相应的硫脲衍生物反应合成了一种结构新颖的标题化合物。该化合物通过元素分析、红外光谱、核磁共振氢谱和粉末X射线衍射(PXRD)分析进行了表征,并通过X射线衍射法对其晶体结构进行了测定。该化合物属于单斜晶系,P21/c空间群,a=12.796 5(11),b=15.391 8(13),c=14.091 5(12),β=92.869(1)。该化合物采用1∶2的平面几何结构进行配位,两个硫原子和两个氧原子围绕在镍(Ⅱ)离子周围。配体中二乙基的无序致使相邻的两个镍原子的距离较长。 The novel title complex, bis[ N-p-chlorobenzoyl-N', N'-diethylthiourea-kS] nickel( II ),was prepared by the reac- tion of nickel nitrate with the corresponding thiourea deriva- tive. It was characterized by elemental analysis, FT-IR, 1HNMR and PXRD,and the crystal structure was determined by X-ray diffraction method. The structure is monoclinie, space group P21/c with cell dimensions a = 12. 796 5( 11 )A, b=15.391 8(13) A,c = 14.091 5(12) AandB=92.869 (1) °. The title compound adopts a 1:2 planar coordination geometry with two sulfur atoms and two oxygen atoms around central Ni( Ⅱ ) ion. The disorder induced by diethyl groups in the ligands leads to a longer distance between two neighbor Ni-Ni atoms.
