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．A detailed synthesis is described for ternary complexes of copper(Ⅱ) α,β-unsaturated carboxylic acids with 1, 1O-phenanthroline. Elementary analysis, IR spectra and thermal analysis show the ternary complexes as CuL2(phen). H2O, where L=CH2 = CHCOOand CH2 = C(CH3)COO-. The molecular structure of Cu (C4H5O2)2 (phen). H2O was 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. 732 2 nm, b= l. 794 8 nm,c=1. 6O14 nm, β=97. 12(2), Z=4.
