A group of copper(II) complexes containing Schiff bases, derived from salicylaldehyde and various amino acids, is interesting due to their biological activities. Structures of (N-salicylidene-rac-glutamato)(1-methylimidazole)Cu(II) I, (N–salicylidene-rac-glutamato)(2-methylimidazole)Cu(II) II and (N-salicylidene-L-glutamato)(2-ethylimidazole)Cu(II) III have been determined. Electron structure of these compounds has been investigated by the B3LYP method.In the all here presented complexes three donor atoms (O, N and O) of the Schiff base and a fourth donor atom from the imidazole ligand (N) define the basal plane of Cu(II). Depending on different substituents R1 and R2 on the imidazole ring, changes of coordination sphere of Cu(II) is varying (square-planar or square-pyramidal) as well as way of packing of molecules in the crystal.
