Notes. Tin-119 and nitrogen-14 nuclear magnetic resonance and tin-119 variable-temperature Mössbauer spectroscopic study of tricyclohexyltin isothiocyanate including the first observation of resolved 117,119Sn–14N coupling in an organotin compound

Abstract

Resolved ^117.119Sn–¹⁴N coupling has been observed for the first time in an organotin compound in tricyclohexyltin Isothiocyanate, with ¹J(¹¹⁹Sn–¹⁴N)= 136 Hz. Variable-temperature Mössbauer spectroscopic data for SnR₃(NCS)(R = C₆H₅ or C₆H₁₁) are interpreted in terms of the tertiary structure of the co-ordination polymer changing from an ‘S’ shape (R = C₆H₅, a=– dln f/dT= 1.84 × 10^–2 K^–1) towards a more linear arrangement (R = C₆H₁₁, a= 1.34 × 10^–2 K^–1).
