Studies on Cu(II), Co(II), Ni(II) and Mn(III) Complexes of Merrifield Resin Supported Ligand and Antimicrobial Activities of this Novel Schiff Base Chelates
نویسنده
چکیده
The Present paper deals with the study of synthesis and characterisation of Cu(II), Co(II), Ni(II) and Mn(III) complexes of polystyrene with 2-aminobenzaldehyde phenyl hydrazone ligand. The study is supported by magnetic susceptibility, infrared and UV-visible spectral study and thermal studies. The ligand and its metal complexes were screened for their antimicrobial activity using S.aureus and E.coli micro organism and found to be moderately active. All the complexes catalyse the decomposition of H2O2, copper(II) complex being the most active.
