Synthesis and characterization of Cu(II) complexes with new mandelic hydrazones

Cu(II) chelates of a series of new derivatives of mandelic hydrazones have been synthesized and characterized using elemental and TG analyses, IR, UV- Visible and EPR spectra. X-ray diffraction patterns were used to study thei r structure and geometry. The study revealed that Cu(ll) complexes can exhi bit square planar, tetrahedral or distorted octahedral structure depending on the nature of the ligands used and the stoichiometric ratio between the metal and ligand.
