1-(2-hydroxylethyl)-2-methyl-5-nitroimidazole (metronidazole) complexes of Fe(II), Ni(II) and Cu(II), were prepared in methanol. The complexes were characterized using melting point, infrared, uv/visible spectroscopy while Job’s spectroscopic mole fraction method was used to establish the stoichiometries of the complexes (M:L). The increase in the melting point of the complexes compared to the free ligand provided evidence for complexation. The 1-(2-hydroxylethyl)-2-methyl-5-nitroimidazole is a bidentate ligand, which coordinated to the Fe(II), Cu(II) and Ni(II) ions through the oxygen of the hydroxyl group and nitrogen of -C=N group giving the complexes of the form M(met)₂(M= Cu) and M(met)₂.2H₂O (M=Fe and Ni) resulting in complexes of mole ratio of 1:2 (M:L). It is found that Fe(II) and Ni(II) formed complexes of octahedral geometries, while Cu(II) formed complexes of square planar geometry, due to the nature and steric disposition of the metronidazole molecule.
