|Abstract:||Mo(VI), and Mo(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: infrared and electronic spectra, magnetic susceptibility, molar conductance measurements, and the metal content in complexes are estimated by gravimetric analysis. Based on this study square pyramidal structure for Mo(IV) complexes and octahedral structure for the Mo(VI) complexes are proposed. The biological activity of these are studied against two strain gram +ve bacteria (Staphalococcus auras, P.aeruginosa) and two strain gram -ve bacteria (E.coli, Enterococcus ) and yeast Candida albicans to assess their inhibiting potential. The results show the two ligands are inactive against Staphalococcus auras and they have moderate activity against the rest microbactrial organisms, the antimicrobial screening show that complex [MoO (Lb)2] exhibit the most activity against the two types of bacteria and the complex [MoO (La)2] exhibit the most activity against the yeast Candida albicans|
