[RE(AGly)_2(Im)_2(H_2O)_3](ClO_4)_3·H_2O多元固体配合物的研究

Study on rare earth complexes containing imidazole and acetylglycine

在甲醇介质中 ,合成了稀土混配固态配合物 [RE( AGly) 2 ( Im) 2 ( H2 O) 3 ]( Cl O4 ) 3 ·H2 O( RE=La,Pr,Nd,Sm,Eu,Gd,Dy ;AGly-乙酰甘氨酸 ;Im-咪唑 )。通过化学分析 ,元素分析确定了配合物的组成 ;利用1H NMR,IR,UV,X-射线粉末衍射等分析 ,并结合 TG- DTG对配合物热分解机理的研究 ,讨论了配合物的配位行为。用 AMI半经验法对配体进行了结构优化 ,计算了它们的电荷分布 ,推测出该类配合物可能的结构。

New solid RE(La,Pr,Nd,Sm,EuGd,Dy,Er)perchlorate ternary complexes containing Imidazole and Acetylglycine have been prepared in methanol .The component of the complexes is determined by using element analysis, chemical analysis. The complex has been characterized by IR, 1H NMR, UV, X ray powder diffraction, TG DTG. And the structure of the complexes is studied.
