Complexes of Fe(III) and Mn(II) with bithiourea were synthesized and characterised by elemental analysis, magnetic measurements, infrared spectroscopy, UV/visible, thin layer chromatography, and conductance measurements. The IR showed that the ligand coordinates through C=S and N–H donor atoms and hence a bidentate. The antimicrobial activity of the complexes formed has been tested and compared with bithiourea at different concentrations in order to obtain some quantitative information about their biological activity towards microorganism. Metal complexes were found to show better activities as compared to the ligand and the standard drug used as control. In vivo toxicological studies showed that the complexes were not toxic at the dosage level administered.
