Abstract

Structure of copper(II) chelates based on glyoxylic hetarylhydrazones containing benzazole (quinoxaline and phthalazine) fragments have been studied by EPR spectroscopy. Spectral parameters in polycrystalline state and dimethylformamide solutions have been determined. Spectral parameters of benzimidazole derivative are typical for square planar structure of the chelate node, while phthalazine derivative displays formation of polymeric structures due to reduction of copper(II) atom.
