摘要: 吡唑啉类化合物具有杀菌特性和植物生长调节作用[1],3-苯基-5-(呋喃-2)吡唑啉二硫代甲酸盐能与许多过渡金属离子形成稳定的配合物[2]。而与稀土的配合物尚未报道。为考察稀土与含硫有机配体形成配合物的条件及该配合物的性质,我们在非水体系和保护气氛中,合成了5种轻稀土元素与3-苯基-5-吠喃-2)毗哩琳二硫代甲酸固体配合物,研究了其组成和性质。

Abstract: Five solid complexes of rare earth with 3-phenyl-5-(furyl-2)pyrazoline dithioformate RE(S2CNC13H11NO)3·nH2O(RE=La, Pr, Nd, Sm, Eu; n=2,4) have been synthesized in dry N2 atmosphere and characterized by elemental analyses, IR spectra, molar con uctance, thermal analyses and fluorescence spectra. The results show that ligands are ccordinated to RE ion through two sulphur atom donors.
