Synthesis and characterisation of some mixed ligands adducts of benzoylacetone and salicylaldehyde

Abstract

A series of four mixed ligand complexes were synthesized by reacting benzoylacetone and salicylaldehyde with different metal chlorides in ethanolic medium. The complexes have been characterized by molar conductance measurements and spectral techniques such as IR and Uv-visible electronic spectra. Decomposition temperature was also determined. The results indicated that the compounds have bands at 400-500cm^-1, with very sharp melting points. This proved the formation of metal-oxygen bond, purity and high thermal stability of the compounds that could lead to a high antimicrobial activity.
