Synthesis, characterization and variable temperature NMR studies on coordination geometry of dimethytin(IV) S(+)-2-(4-isobutylphenyl)propanoate

Dimethytin(IV) S(+)-2-(4-isobutylphenyl)propanoate was synthesized and characterized by elemental analysis and IR and variable temperature NMR spectroscopy. Variable temperature NMR analysis was performed to see the effect of temperature on coordination geometry of organotin complexes in non-coordinating solvent. Spectral data has shown that temperature change does not alter the coordination geometry of the complex, and that it remains greater than four at variable temperatures as well as at room temperature in solution state.
