A new class of triazole Schiff bases have been prepared by the reaction of 3,5-diamino-1,2,4-triazole with methyl-, chloro-, and nitro-substituted furan-2-carboxaldehydes in an equimolar ratio (1 : 1). The bidentate ligands were characterized by IR, 1H-, and 13C-NMR, microanalysis, and mass spectrometry. The Schiff bases were complexed with vanadyl(IV) sulfate in a molar ratio (M : L) 1 : 2, [M(L)2]SO4 (where L = L1-L5 and M = VIVO) in a square-pyramidal geometry. Invitro antibacterial activity was determined by screening the compounds against four Gram-negative (Escherichia coli, Shigella flexenari, Pseudomonas aeruginosa, and Salmonella typhi) and two Gram-positive (Staphylococcus aureus and Bacillus subtilis) bacterial strains and in-vitro antifungal activity was carried out on Trichophyton longifucus, Candida albican, Aspergillus flavus, Microscopum canis, Fusarium solani, and Candida glaberata strains.
