The two ligands include thiocarbohydrazone bis-2-hydroxyacetophenone (HAPTC) (1) and thiocarbohydrazone bis-2-furfural (FTC) (2) were synthesized by reacting the corresponding ketones and primary amines. Subsequently, two series of organotin(IV) complexes have been synthesized by direct reactions of RnSnCl4-n (R = Me, Bu, Ph; n = 1, 2), base and ligands (1-2) in 1:1:1 or 1:2:1 mole ratios. All ligands and their organotin(IV)complexes (3-13) have been characterized by elemental analyses, molar conductivity, UV-visible, IR, NMR spectroscopy and X-ray single crystal analysis. Based on the spectral studies, the ligands (1-2) was coordinated to tin(IV) via its ONS-donor atoms. Biological activity of the synthesized ligands and their organotin(IV) complexes were tested against Artemia salina, Coptotermes sp. and various bacterial stains. Biological ... |
