Two novel dithiophosphonate ligands, HS2P(p-C6H4OMe)(OCH2CH2CH(CH3)2) (1) and HS2P(p-C6H4OMe)(OCH(CH3)2) (2), were synthesized and characterized by multinuclear (1H, 31P, and 13C) NMR, infrared spectroscopy as well as elemental analysis. The reactions of 1 and 2 with NiCl2·6H2O and Cd(NO3)2·4H2O in methanol led to novel complexes 3 and 4. The single crystal X-ray structures of 3 and 4 showed tetracoordinated structure with square planar geometry for the nickel complex, while it showed pentacoordinated structure with distorted square-pyramid environment for the cadmium complex.

衍生自二硫代膦酸盐的 Ni(II) 和 Cd(II) 配合物的合成、表征和分子结构

合成了两种新型二硫代膦酸酯配体，HS2P(p-C6H4OMe)(OCH2CH2CH(CH3)2) (1) 和 HS2P(p-C6H4OMe)(OCH(CH3)2) (2)，并通过多核 (1H, 31P,和 13C) NMR、红外光谱以及元素分析。1 和 2 与 NiCl2·6H2O 和 Cd(NO3)2·4H2O 在甲醇中的反应产生了新的配合物 3 和 4。3 和 4 的单晶 X 射线结构显示镍配合物为四配位结构，平面几何形状为正方形，而镉配合物显示出五配位结构和扭曲的方形金字塔环境。
