Studies on Co2+, Ni2+ and Cu2+ Complexes with Schiff Bases Derived from Benzil Monohydrazone

Abstract

The synthesis of Co²⁺, Ni²⁺ and Cu²⁺ complexes of Schiff bases derived from the condensation of ethanolic solution of benzil monophenyl hydrazone with aniline and substituted anilines (in presence of H₂O, α,β,γ picoline and pyridine). The complexes are characterized by elemental analyses, magnetic, IR, electronic, mass spectra and thermal studies. The schiff base behaves as a tridentate ligand. Spectral studies shows the dimeric nature of complexes.
