摘要： 合成了丙烯酸铜和α-甲基丙烯酸铜与1,10-邻菲绕啉形成的三元配合物,通过元素分析、红外光谱、热谱等数据对配合物进行了表征.测定了Cu(C4H5O2)2(phen)·H2O的晶体结构.配合物的组成为CuL2(phen)·H2O(L=CH2＝HC-COO-,CH2=C(CH3)-COO-),结构为畸变的四方锥形,属单斜晶系,P21/n群,晶胞参数:a=0.7322nm,b=1.7948nmc=1,6014nm,β＝97.12(2)°;Z＝4.

Abstract: Adetailed synthesis is described for ternary complexes of copper(Ⅱ) α,β-unsaturated carboxylic acids with 1, 1O-phenanthroline.Elementary analysis, IRspectra and thermal analysis show the ternary complexes as CuL2(phen).H2O, where L=CH2=CHCOO and CH2=C(CH3)COO-.The molecular structure of Cu (C4H5O2)2 (phen).H2Owas determined by single crysta1 X-ray diffraction, the result of which shows that the complex ismononuclear with distorted square pyramidal coordination from two monodentatecarboxylates, a bidentate 1,10-phenanthroline and one aquo ligands.The crystal is monoclinic with space group P21/n and unit cell parameters are: a=O.7322 nm, b=l.7948 nm,c=1.6014nm, β=97.12(2), Z=4.
