Synthesis, Characterization and Antimicrobial Studies of Schiff Base Complexes of Arsenic(III), Antimony(III) and Bismuth(III) Chloride

摘要

In this study, thioacetamide and salicylaldehyde were condensed together to form 2-(thioacetylimino)methyl]phenol (LH), which further reacts with metals As (III), Sb(III) and Bi(III) chloride in ratio of 1:1 and 2:1respectively, to form complexes. All these were characterized by ~(1)HNMR, ~(13)CNMR and IR spectroscopy, elemental analysis and reported literature studies. On the basis of all supporting information, all metal complexes (M/L) in 1:1 (ML_(1)) and1:2 (ML_(2)) showed 4 and 5 coordinated geometry, distorted trigonal bipyramidal and distorted octahedral, respectively. These complexes showed good antibacterial, antifungal and antitubarcular activities.
