Abstract

Mononuclear nickel(II) complex, viz. [Ni(L)(PPh(3))] (where L is dianion of N-(2-mercaptophenyl)-4-methoxysalicylideneimine) has been synthesized and characterized by means of elemental analysis, electronic, IR and NMR [(1)H, (13)C{(1)H} and (31)P{(1)H}, DEPT, (1)H-(1)H COSY, ge-HSQC, ge-HMBC] spectroscopic techniques. Structural analysis of the complex by single crystal X-ray crystallography indicated the presence of square planar coordination geometry (ONSP) about nickel. One of the phenyl rings of triphenylphosphine involve in C-H...pi interactions with H6b, H13 and H32 to form a three dimensional network which stabilizes the structure of complex.

摘要

单核镍（II）配合物，即 [Ni(L)(PPh(3))]（其中 L 是 N-(2-巯基苯基)-4-甲氧基水杨醛亚胺的二阴离子），已通过元素分析、电子、IR 和 NMR [（1）H、（13）C{(1)H} 和（31）P{(1)H}、DEPT、（1）H-(1)H COSY、ge-HSQC、ge-HMBC]光谱技术进行了合成和表征。通过单晶 X 射线晶体学对配合物的结构分析表明，镍具有正方形平面配位几何形状（ONSP）。三苯基膦的一个苯基环与 H6b、H13 和 H32 发生 C-H...pi 相互作用，形成一个三维网络，从而稳定了配合物的结构。
