Mn(II) complexes of Schiff bases 4-((3-ethoxy-2-hydroxybenzylidene)amino)-N-(pyridin-2-yl)benzenesulfonamide (HL2) and 4-((3-ethoxy-2-hydroxybenzylidene)amino)-N-(pyrimidin-2- yl)benzenesulfonamide (HL3) were synthesized. The Schiff bases HL2 and HL3 and their complexes were characterized by analytical, conductance, magnetic susceptibility measurements, infrared, ultraviolet-visible, thermal analysis, and EI mass techniques. The spectral data of the complexes have revealed the bidentate complexing nature of the Schiff base ligand through phenoxide ion and azomethine nitrogen atoms. The antibacterial activities of complexes were tested against gram-positive bacterial species Pseudomonas aeruginosa (NCIM 2036) and fungal species Aspergillus niger (NCIM 105) and Mucor sp. (NCIM 108) by disc diffusion method.
