摘要: Abstract A new unsymmetrical Schiff base ligand (H2L) was derived from the 1:1 M condensation of 2,3-dihydroxybenzaldehyde with allylamine. Molybdenum(VI) complex, MoO2L2, synthesized reaction MoO2(acac)2 in a 1:2 ratio methanol at ambient temperature. The and its Mo(VI) complex were characterized by elemental analyses, FT-IR, 1H NMR, 13C NMR UV–Vis spectroscopies single crystal X-ray analysis. molecular structure schiff showed pseudo-scorpionate solid state. MoO2L2 adopts an octahedral environment around Mo center cis-oxo configuration. other coordination sites are occupied hydroxyl oxygen atoms two ligands. interaction investigated theoretical calculation. also tested for their vitro antimicrobial activity against Staphylococcus aureus (ATCC 29737) Pseudomonas aeroginosa (PTTC 1570) as examples Gram-positive Gram-negative bacterial strains, respectively, disc diffusion method. results indicated that had better antibacterial than surprisingly, they synergistic when used P. PTTC 1570.
