Studies on the Complexes of Rare Earth with Organic Ligands Containing Sulphur Atoms (Ⅷ)——Synthesis and Properties of Poly nuclear Complexes of Rare Earth Acetates with Nickel Glycinemethanedithioate

在乙醇—水溶液中,用稀土醋酸盐与氨基乙酸二硫代甲酸镍[H_2Ni(Gc)_2]反应,制备出14种稀土元素的多核配合物,通过元素分析确定了配合物的组成为RENi(Gc)_2·AC·H_2O(RE=La—Gd,除Ce、Pm外)和RE_2[Ni(Gc)_2]_3·xH_2O(RE=Tb—Lu,Y;x=4,8,10),研究了配合物的溶解性、红外光谱、X射线光电子能谱和核磁共振氢谱。

The new polynuclear complexes of rare earth acetates with nickel gly-cinemethanedithioate were synthesized in the aqueous alcohol solution and characterized by elemental analysis, solubility, infrared spectra, X-ray photoelectron spectroscopy and 'H NMR. The results show that the composition of the complexes are RENi(Gc)2Ac.H2O(RE = La-Gd, except Ce, Pm; Gc=glycinemethanedithioate) and RE2[Ni(Gc)2]3.xH2O(RE = Tb-Lu, Y; x = 4,8,10).
