Copper(II) complexes based on N-(2-carboxyethyl)alkanolamines

Abstract

A comparative study of the copper metallocenter coordination sphere is carried out for a series of N-substituted β-alaninate ligands in condensed phase. For the elucidation of the effect of regular changes in dentate properties of a ligand on the complex structure, N-(bis(hydroxymethyl)methyl)- β-alanine and its copper(II) complex are specially synthesized and the complex structure is studied by the method of X-ray structural analysis. For determination of structure of the complexes in aqueous solution is applied electron spin resonance spectroscopy. Structural characteristics of β-alaninate and glycinate complexes are compared. The factors promoting formation of polynuclear complexes are considered. © 2009 Pleiades Publishing, Ltd.
