<p>Two new Schiff base ligands formed by the condensation of 5-bromosalicylaldehyde with sulfapyridine and sulfathiazole and their metal complexes of Co<sup>II</sup>, Ni<sup>II</sup> and Cu<sup>II</sup> were synthesized and characterized by elemental analysis, molar conductance, thermal studies, magnetic moment, EPR, IR, <sup>1</sup>H NMR, <sup>13</sup>C NMR, mass and electronic spectral data. Both ligands are bidentate, coordinating through azomethine nitrogen and hydroxyl oxygen after deprotonation. These compounds were screened for in vitro antibacterial activity against Gram-positive (<em>Staphylococcus aureus, Bacillus subtilis</em>), Gram-negative (<em>Pseudomonas aeruginosa</em>, <em>E.</em> c<em>oli, Klebsiella</em> sp.) bacterial strains and for<em> in vitro</em> antifungal activity againt <em>Aspergillus niger</em>, <em>Mucor</em> sp. and <em>Candida albicans</em>. The results of these studies revealed that all complexes exhibited significant to moderate antibacterial activity. All the complexes exhibit six coordinated octahedral geometry.</p>
