Complex Anti-microbial Ability of Salicylaldehyde Thiosemicarbazone towards ZnII, AgI & LaIII Ions
Abstract
Three mono, di, and tri valance novel complexes of Zn2+, Ag+, and La+3of the general formula [M [L]3(H2O)]; were designed and synthesized directly with excellent yield via reaction between thiosemicarbazide linked and 2-hydroxybenzaldehyde or (Salicylaldehyde) under optimized heat reaction conditions. . Furthermore, the finding products that follow Schiff bases were elucidated by IR, UV, and 1H-NMR spectroscopy. Likewise, the antibacterial activities of the ligands and their complexes were determined by in vitro assays against Gram (+Ve) and Germ (-Ve) bacterial strains besides fungi agents. The results evaluated that the complexes contain leading functional groups such as (OH, NH2, C=S, C-O, and C=N). The behaviour of the complexes as anti-biology against bacteria and fungi has been scrutinized. The results displayed that Zn2+ can degrade Garm (+Ve) S. aurues Bacillus. However, the Ag+ complex illustrates high resistance to the same germ, and La3+ moderately affects bacteria and fungi.
