Synthesis and Biological Activities of organotin Schiff Base Complexes Год выпуска: 2014Автор: Iftikhar Hussain Bukhari,Imtiaz Ahmad and Jeveria RehmanИздательство: LAP Lambert Academic PublishingСтраниц: 84ISBN: 9783659560644Описание 2-Thiophenecarboxylic acid hydrazide has been treated with benzaldehyde in 1:1 molar ratio at room temperature in the presence of a suitable solvent to yield Schiff base. Then it has been treated with R2SnCl2/R3SnCl in 1:1 molar ratio to synthesize organotin(IV) complexes under reflux conditions. Organotin(IV) complexes have been characterized by FT-IR and semi-empirical study. FT-IR data explains the tetrahedral arrangement of sulphur donor ligand with tin metal which is further confirmed by semi-empirical study. Least value of dipole moment of complex 3 explain the trans orientation of chlorine atom around tin metal. The complexes along with ligand have also been screened for their antibacterial and antifungal activities. Organotin(IV) complexes exhibited antibectrial activities with few exceptions as compared to free ligand. Complex 4 has been found potent antibacterial agent among all complexes.
