摘要
本文以反式２－羟基－４－（１－甲庚基）二苯甲酮肟（Ｎ５３０）萃取镍，采用等摩尔系列法、萃取饱和容量法、萃取斜率法及萃合物的元素分析测出反式羟肟萃取镍的配合物组成为ＮｉＬ＿２，根据配合物的ＵＶ、ＩＲ、ＮＭＲ光谱结果，对萃合物结构进行了探讨。推测该配合物为反式平面构型，羟肟分子的酚基氧与镍形成共价键，肟基氮与镍形成配位键。配合物分子内配体肟羟基彼此与对方的酚基氢形成较强的分子内氢键作用。
In this paper we studied the Ni(Ⅱ) complex of 2-hydroxy-4-(1-methylheptyl) benzophenone oxime( N5 30) with pure anti form extractant. The composition of the extracted complex has been determined to be NiL_2(HL=extractant, N530) by saturation method、isomolar method、slope analysis and elemtary analysis. The sturcture of the complex has been discussed on the besis of UV、NMR and IR spectra.
