<p>Oxovanadium(IV) and dioxouranium(VI) complexes of a Mannich base derived from morpholine, benzaldehyde and semicarbazide hydrochloride have been synthesized and characterized. The probable structures of these complexes were elucidated by elemental analysis, molar mass, molar conductance, spectral and X-ray diffraction studies. The formulae exhibited by complexes are: [VO(MBS)2]·2H2O and [UO2(MBS)2(H2O)2], where MBS = N-(1-morpholinobenzyl)semicarbazide. The biological activities of ligand and metal chelates against S. aureus, K. pneumoniae, P. vulgaris and E. coli were also investigated. The metal chelates have higher activity than that of free Mannich base, N-(1-morpholinobenzyl)semicarbazide.</p>
