Synthesis of some novel divalent transition metal complexes as antimicrobials

A novel series of transition metal complexes have been synthesized from the reaction of 5-((3-(methylthio)-5-(pyridin-4-yl)-4H-1,2,4-triazol-4-ylamino)methyl)quinolin-8-ol with transition metal salts. The structures of these compounds have been elucidated by elemental and spectral analysis. Furthermore, compounds were screened for in vitro antimicrobial activity against the representative panel of two Gram-positive and two Gram-negative bacteria and two strains of fungus. The various compounds show potent inhibitory action against test organisms.
