【 摘 要 】

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.
