Synthesis, structural elucidation and biological activities of organotin(IV) derivatives of 4-(2-thienyl)butyric acid

A series of tri- and diorganotin(IV) derivatives of 4-(2-thienyl)butyric acid have been synthesized by the reaction of ligand acid with tri- and diorganotin salts in 1:1 and 2:1 molar ratios, respectively. The synthesized compounds have been confirmed by CHNS elemental analyses, FTIR, multinuclear NMR (1H and 13C) spectroscopy and X-ray diffraction studies. NMR data reveal a 5-coordinate geometry for the triorganotin(IV) derivatives, while...
