Magnesium [II] complexes of schiff bases of two beta- lactum antibiotics: synthesis and spectral characterization

Two Mg [II] complexes have been synthesized by condensing magnesium chloride with schiff bases of two different beta-lactams. In the present study, cephalexin and cefadroxil were the beta-lactams used for the synthesis of complexcs through schiff base formation. The estimation of carbon, hydrogen. nitrogen and sulphur, percentage of magnesium, and measurcments of IR spectra at 400- 4000cm[-1] indicated the formation of coordination compounds. The ratio of 2:1 complex of schiff base ligand to metal was confirmed through Job's of continuous variation. Further characterization of the complexes was carried out using UV spectra, mass spectra and conductance measurement
