SYNTHESIS OF MACROCYCLIC LIGANDS AND THEIR COBALT(II) COMPLEXES SPECTRAL CHARACTRIZATION AND ANTIMICROBIAL STUDIES
AbstractComplexes of Co(II) with macrocylic ligands i.e., 2, 3, 9, 10 tetraphenyl – 1, 4, 8, 11 – tetraazacyclotetradeca – 1, 3, 8, 10 tetraene (BDP), 2, 4, 10, 12 – tetramethyl – 1, 5, 9, 13 tetraazacyclohexadeca 1, 4, 9, 12 tetraene (ADP), 2, 3, 9, 10 tetramethyl 1, 4, 8, 11 tatraazatetredeca – 1, 3, 8, 10 tetraene (DDP) have been synthesized. All these complexes were characterized by elemental analysis, molar conductance magnetic susceptibility measurement, electronic and epr spectral studies. On the basis of elemental analysis the complexes were found to have composition CoLX2. Molar conductance measured in DMF solution indicates that complexes are non-electrolytic in nature except Co(BDP)SO4 which are 1 : 2 electrolytes. Thus the complexes may be formulated as [CoCLX2]. Magnetic moments and the electronic spectra indicate six coordinated distorted octahedral geometry for the complexes. The ligand field parameters were calculated using various energy level diagrams. In vitro synthesized compounds and metal salts have also been tested against same species of plant pathogenic fungi and bacteria in order to assess their microbial properties.
