Novel complexes of Co(II), Ni(II) and Cu(II) with paracetamol and 1,10- phenanthroline have been synthesized and characterized using infrared spectroscopy, mass spectrometry, electronic absorbance, melting point and conductivity measurements. The two ligands have been found to act as bidentate chelating agents. Paracetamol coordinates through the carbonyl group and nitrogen atom of amide group, while1,10- phenanthroline coordinates through the two nitrogen atoms. Based on magnetic moment and electronic spectral studies, an octahedral geometry has been assigned for the complexes. Antibacterial screening of the complexes against some gram positive and negative bacteria was tested.
