锗(Ⅳ)与邻苯二酚和含氮配体混配配合物的合成与表征

SYNTHESIS AND CHARACTERIZATION OF MIXED LIGAND COMPLEXES OF GERMANIUM(Ⅳ) WITH CATECHOL AND N LIGAND

首次合成了四种锗（Ⅳ）与邻苯二酚和α－氨基酸的混配配合物［Ｇｅ（Ｃ６Ｈ４Ｏ２）２·２ＡＡ］，（ＡＡ＝α－甘氨酸（ｇｌｙ）、α－苏氨酸（ｔｈｒｅ）、α－缬氨酸（ｖａｌ）、α－白氨酸（ｌｅｕ）；两种锗（Ⅳ）与邻苯二酚和杂环二胺类的混配配合物［Ｇｅ（Ｃ６Ｈ４Ｏ２）２·（ＤＡ）］，（ＤＡ＝２，２′－联吡啶（ｂｉｐｙ）、１，１０－邻菲咯啉（ｐｈｅｎ）。用元素分析、摩尔电导、红外和紫外光谱、核磁及热分析等方法研究了配合物的组成和性质，表明配合物有两种结构类型，一类是反式八面体，另一类为顺式畸变八面体。

Four new mixed ligand complexes of germanium (Ⅳ) with catechol and α aminoacid (AA=glycine, threonine, valine and leucine), and two new mixed ligand complexes of germanium (Ⅳ) with catechol and hybrid ring diamine (DA=2,2′ bipyridine and 1,10 phenanthroline) were synthesized and characterized by elemental analyses, infrared and electronic spectra, molar conductance, 1H NMR and thermal analyses The compositions of the copmlexes were confirmed to be [Ge(C 6H 4O 2) 2·2AA] and [Ge(C 6H 4O 2) 2·(DA)] Some properties of the complexes were studies
