Synthesis and characterization of novel Organosilicon (IV) complexes with pyridine dicarboxylic acid and Mercapto pyridine carboxylic acid
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2011, Vol 1, Issue 2
Abstract
New Organosilicon (IV) complexes of ligands H2La (Pyridine dicarboxylic acid) and H2Lb (Mercapto Pyridine carboxylic acid) with R2SiCl2 & RSiCl3 (where R=Me, Et, Ph) were synthesized in the presence of sodium methoxide and triethylamine, respectively. The prepared organosilicon complexes were characterized by analytical, molar conductance and spectroscopic techniques including IR, 1H, 13C and 29Si NMR. On the basis of these studies, the resulting complexes have been proposed to have trigonal bipyramidal and octahedral geometries. The ligands and their organosilicon complexes have been evaluated for in-vitro antimicrobial activity against bacteria (Bacillus subtilis, Staphyllococus aurus, and Escherichia coli) and fungi (Aspergillus Niger and Candida albicans). The complexes were found to be more active than their respective ligands.
