Some new mixed ligand complexes of the type [M(Fu)2B], where M is Ni (II) or Co(II), FU is furfural urea and B is ammonia were synthesized characterized by metal analysis, solubility test, melting/decomposition point, conductivity measurement, IR and UV/VIS spectroscopy. The mixed ligand complexes were also tested for their antimicrobial activity against Escherichia coli, Staphlococcus aureus and Salmonella paratyphi. There was evidence of coordination between the metals and the ligands and the electronic spectra suggested an octahedral and tetrahedral geometry for the Ni(II) and Co(II) complexes respectively. All the complexes recorded appreciable activity against all the test organisms.
