Solution studies of copper(II) complexes as a contribution to the study of the active site of galactose oxidase

the synthesis and solution characterization of the coordination compounds - [cuii(h2bbpeten)](no3 )2, [h2bbpeten = n-(2-hydroxybenzyl)-n,n'-bis(2-pyridylmethyl)- n'-(2-hydroxyethyl)ethane-1,2-diamine]; [cuii(h3bpeten)](no3 )2, [h3bpten = n,n'- bis- (2-hydroxybenzyl) -n-(2-pyridylmethyl)-n'-(2-hydroxyethyl)ethane-1,2-diamine]; [cuii(hnbbpeten)]no3, [h2nbbpeten = n-(5-nitro-2-hydroxybenzyl)-n,n '-bis(2- pyridylmethyl)-n'-(2-hydroxyethyl)ethane-1,2-diamine] and [cuii(hbnbpeten)], [h3bnbpeten = n,n'-bis-(5-nitro-2-hydroxybenzyl)-n -2-pyridylmethyl)-n'-(2-hydroxyethyl)ethane-1,2-diamine] - are reported as copper(ii) complexes containing alcoholic, pyridine and phenolic arms. two of the ligands bear a no2 group at the para position of one or two of the phenolic moieties. electrochemical studies have been performed for the proligands and for the copper complexes.
