Abstract

The Schiff bases obtained from formylmenthone and some aromatic amines behave as bidentate ligands with O and N donor atoms in Cu(II) complexes of the type CuL₂(CH₃OH)₂, CuL₂, (CuLCH₃COO)₂ or as monodentate ligand, CuL₄(CH₃COO)₂. The donor atoms and the possible geometry of the complexes were assigned by means of chemical analyses, electronic, EPR and IR spectra and conductivity measurements.
