摘要
在乙醇水溶液体系中合成了8种新的稀土吲哚-3-乙酸和吲哚-3-丁酸配合物,其通式为Ln(lA)_3·2H_2O和Ln(IB)_3·2H_2O(Ln=La,Nd,Sm,Er;IA=C_(10)H_8NO_2;IB=C_(12)H_(12)NO_2)。用元素分析、电导测定、电子吸收光谱、红外光谱、X光电子能谱和热重-差热分析确定了配合物的组成和成键特性。
Eight new solid complexes of rare earth ( Ⅲ ) with indole-3-butanoicacid and indole-3-bu-tanoic acid were synthesized in ethanol-water soluton. The new complexes have the composition Ln (IA)3·2H2O and Ln(IB)3·2H2O(Ln = La,Nd,Sm,Er,IA = C10H8NO2, IB = C12H12NO2). The electronic spectra of the complexes were observed. The molar conductance data show that the complexes are non-electrolyte. IR spectra and XPS measurements indicate the unidentate coordination mode of carboxylate ions to rare earth (Ⅲ ) ion in Ln(IA)3 · 2H2O compounds and the bidentate coordination mode of carboxylate ions in Ln(IB)3 · 2H2O compounds, also show that nitrogen atoms in indole-3-acetates are coordinated, but nitrogen atoms in indole-3-butanoates are uncoordinated. The TG-DTA data show that the complexes are all relatively stable thermally.
