Article abstract of DOI:10.1107/S0108270196000583

The synthesis, structure and ¹¹⁹Sn NMR spectrum of the title compound, (C₄H₁₂N)[Sn(C₇H₅OS)₃], are reported. Crystallographic threefold symmetry is present in both the anion and cation. In the [Sn(SOCPh)₃] anion, the Sn^II coordination geometry is triangular pyramidal, with the S atoms forming the basal plane and the Sn atom at the apex; the Sn - S distance is 2.592 (2) A. In addition, weak intramolecular interactions occur between the Sn atom and the carbonyl O atoms [Sn...O 2.967 (2) A]. The ¹¹⁹Sn NMR chemical shift of the title compound is -227 p.p.m. (MeCN, 295 K).
