The complexes were synthesised and characterized by magnetic measurements, EPR and reflectance electronic spectroscopy.The crystal structure of has been determined by X-ray diffraction: it consists of discrete units in which a very asymmetric CuN2O2O'2 chromophore is present with the two nitrogen atoms from 2,9-dmphen nearly symmetrically chelated , two carboxylic oxygens of a bidentate dmc molecule , and the oxygen atom of a monodentate carboxylic acid group of a second dmc molecule.Copper deviates from the 2,9-dmphen plane by 0.1811(7) Angstroem and the carboxylic acid groups lie on planes roughly orthogonal ; the second carboxylic oxygen of the monodentate dmc molecule is involved in a long contact with the metal .
