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。
In ethanol - aqueous solution, rare earth acetate and nickel dithiocarbamate [H_2Ni (Gc) _2] were reacted to prepare 14 kinds of rare earth elements of polynuclear complexes, by elemental analysis to determine the composition of the RENi (Gc) _2 · AC · H_2O (RE = La-Gd except Ce and Pm) and RE_2 [Ni (Gc) _2] _3 · xH_2O (RE = Tb-Lu, Y; The solubility, IR, XPS and 1H NMR spectra of the complexes were studied.
