|Abstract:||Mn(II), Mn(III), and Mn (IV) complexes with two Schiff base ligands derived from salicylic acid hydrazide with 4-dimethylaminobenzaldehyde and 4-Nitrobenzaldehyde have been prepared and characterized by several techniques, including, infrared and electronic spectra, magnetic measurements, molar conductance measurements, and the metal content in complexes were estimated by gravimetric analysis. Based on these studies square pyramidal structure for Mn (III) complexes and octahedral structure for the Mn (II) and Mn (IV) complexes were proposed. The antimicrobial activity against two Strain Gram +ve bacteria (Staphalococcus auras, Enterococcus) and two Strain Gram -ve bacteria (E.coli, P.aeruginosa) and yeast Candida albicans to assess their inhibiting potential, the results showed all ligands and their complexes inactive against Staphalococcus auras and they have moderate activity against the rest microorganisms|
