Synthesis, spectral characterization and thermal studies of Ti (III), Cr (III) and Mn (III) complexes derived from 2-Chlorobenzohydrazone schiff’s base

Author(s): Suchita B. Wankhede and Arun B. Patil

Tridentate Schiff’s base ligand, H2L (1-(1-hydroxynaphthalen-2-yl)ethanone-2-chlorobenzoylhydrazone) and their metal complexes with Ti (III), Cr (III) and Mn (III) ions have been synthesized and characterized by elemental analysis, 1H NMR, IR, electronic spectroscopy, magnetic susceptibility and molar conductance. From analytical and spectral data, the stiochiometry of complexes has been found to be (1:1) (metal:ligand). The physicochemical data suggest octahedral geometry for Ti (III), Cr (III) complexs and square pyramidal geometry for Mn (III) complex. Thermal stabilities of the complexes have been studied by thermogravimetric analysis.
