Synthesis,Characterization and Crystal Structure of Ternary Complexes of Copper(Ⅱ) α,β-Unsaturated Carboxylic Acids with 1, 10-Phenanthroline

Abstract

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.

Key words: Copper (Ⅱ) α,β-unsaturated carboxylic acid, 1,10-Phenanthroline, Ternary complex, Crystal structure
