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

摘要

Cu(II) chelates of a series of new derivatives ofmandelic hydrazones have been synthesized and characterizedusing elemental and TG analyses, IR, UV-Visible and EPR spectra.X-ray diffraction patterns were used to study their structure andgeometry. The study revealed that Cu(II) complexes can exhibitsquare planar, tetrahedral or distorted octahedral structuredepending on the nature of the ligands used and the stoichiometricration between the metal and ligand.
