✦ Synopsis

Copper(II) complexes of the general composition Cu(ligand)2X2 (where X = Ci-, Br-, NO~-, CIO~and -~ SOl-) and Cu(ligand) (CH3COO)2 have been synthesized with methyl n-pentyl ketone and methyl n-hexyl ketone semicarbazones. All the complexes prepared have been characterized by elemental analysis, magnetic moment, molar conductance, IR, electronic and electron spin resonance spectral studies. The complexes Cu(ligand)2X2 (X = CI-, Br-, NO3-) and Cu(ligand) (CH3COO)2 may have tetragonal geometry, while the complexes Cu(ligand)zX2 (X=CIO~-and ~} SOl-) may be assigned a five-coordinated trigonally distorted square pyramidal geometry.
