A series of five monomeric and polymeric complexes: [Bu3Sn(C5H4O2S)] (1), [Me3Sn(C5H4O2S)] (2), [Cy3Sn(C5H4O2S)] (3), [Bu2Sn(C5H4O2S)(2)] (4), [Oct(2)Sn(C5H4O2S)(2)] (5) of thiophene-2-carboxylic acid have been synthesized by the reaction of ligand acid with di- organotin compounds for the complexes 4, 5 and its sodium salt with tri-organotin compounds for the complexes 1, 2 and 3 respectively, in suitable stoichiometries. All complexes have been structurally characterized by vibrational and magnetic resonance (H-1, C-13 NMR) spectroscopies. The structures of complexes (2), (3) and (4) have also been elucidated by X-ray crystallography. Relative potential has been assessed for their anti-bacterial, DNA protection and inhibitory assay against acetyl cholinesterase and butyryl cholinesterase. (C) 2012 Elsevier B.V. All rights reserved.
