Abstract
A series of bioactive cobalt(III) complexes were synthesized with bidentate ligand have been investigated
as vitamin B12 models. The experiment was two pot snythesis, in the first part was green microcrystalline
dihalo(dimethylglyoximato)cobalt(III) and second part was brown microcrystalline halo(pyridine based
ligand) cobaloximes. Final part of synthesized complexes was characterized by IR, electronic and
NMR spectral studies. Infrared spectra of metal complexes indicated the formation of Co-N axial
bond and Co-N equatorial bond. Thermal analysis revealed that the Co(III) complexes were stable up
to 350 ºC. The experimental results of antimicrobial were showed good zone of inhibition towards
selected microbes.
