Studies on Some Transition Metal Complexes with LlX:84

Abstract

The research work presented in this thesis deals with the preparation and characterization of some new complexes of the second transition metal ions (Zr4+, Ag+ and Cd2+) with the new solvent execration reagent, LIX84 (i.e.,2-hydroxy-5- nonylacetophenone oxime) as a ligand. For their synthesis, the prepared aqueous solutions of the metal chlorides (for Cd (II), nitrate) are allowed to react with an n-hexane solution of LIX84 (containing KOH) in different ratios. The prepared complex.es have been characterized by conductivity and magnetic measurements, infrared spectra and electronic spectral studies. Their percent solubilities in various organic solvents and decomposition temperatures have been measured. The molecular weight of the complexes has also been determined by the cryoscopic method.
