摘要： 有机酸性膦(磷)酸酯与二价铜离子的萃合物研究已有报导[1-3]。文献[1]对该萃合物的结构做了初步讨论,认为由于在正庚烷溶剂中铜萃合物的吸收光谱呈一宽的吸收带,最大吸收峰位置在13600cm-1处,难以推断该萃合物是四面体还是平面正方形结构。本文在291和77K下测定了萃合物的ESR谱,并用量子化学的CNDO/2方法对该萃合物的电子结构作了进一步研究。

Abstract: ESR spectra of the copper(Ⅱ) complex with 2 -ethylhexyl phosphonic acid mono (2 -ethylhexyl) ester have been recorded at 291K and 77K respectively.The possible structureshave been proposed based on the results obtained by CNDO/2 method.The metal ion iscoordinated with oxygen atoms of ligand to form a square-planar structure and the comp-lex is arranged into a layered structure of elongated octahedra.Cu—O bond in the complexshows both ionic and covalency property.

Key words: ESR, 2-ethylhexyl phosphonic acid mono(2-ethylhexyl) ester, Cu(Ⅲ)ion, complex
