Synthesis and Spectroscopic Analysis of the Nature of Coordination Modes of Ligands in Copper (ll) and Cadmium (ll) Complexes of Two N-Oxidobenzamide Derivatives

N-Oxidobenzamide derivatives are powerful metal ion chelators. It is used as inhibitors of hypertension, tumor growth, in？ammation, infectious agents, asthma, arthritis, Alzheimer’s diseases and more. In this study, Copper (ll) (SRC1 and SRC3) and Cadmium (ll) (SRC2 and SRC4) complexes were synthesized from potassium N-Oxidobenzamide derivative ligands and they were characterized by using various techniques such as Infra-Red spectra, electronic spectra, melting point and conductivity measurements. The electronic spectral study and the melting point analysis revealed that the ligands are coordinated to the metal centre. IR and conductivity analyses confirm the coordination of hydroxamate ions to the metal centre as O, O-bidentate mode via the hydroxyl oxygen and the carbonyl oxygen atoms of the ligands. The proposed molecular structures for the newly formed complexes are also given.
