AbstractThe stannocanes of the type [O(CH2CH2S)2SnR2](R=Me1,Bun2,Ph3) have been synthesized in an improved method by the reaction of R2SnCl2 with 2, 2′-oxydiethanethiol O(CH2CH2SH)2 in molar ratio of 1:1 at the presence of sodium ethoxide in anhydrous ethanol. The reactions are carried out under inert atmosphere. These compounds have been extensively characterized by FT-IR, UV-Vis spectrophotometry, multi-nuclear (1H, 13C, 119Sn) NMR, elemental analysis and mass spectrometry. The obtained data clearly indicates that, there is a strong interaction between oxygen atom of the ligand as a donor and Sn atom of the organotin species as a Lewis acid acceptor. Therefore, the resulted dithiostannocanes possess a transannular secondary bonding and hypervalency at the central Sn atom which leads to an increase in the coordination number of tin from four to five-coordinated tin.
