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 resolved117,119Sn–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).
