Tetrel bond in the triphenyltin(IV) chloride-cyclo-hexyl-diphenyl-phosphane oxide (1/1) cocrystal.

ABSTRACT: The single-crystal X-ray diffraction structure of the title compound, [SnCl(C₆H₅)₃]·C₁₈H₂₁OP, is reported. The 1:1 cocrystal features a short and directional tetrel bond between tin and oxygen. The tin-oxygen distance is 2.346 (4) Å, representing 62% of the sum of the van der Waals radii of Sn and O. The Cl-Sn⋯O angle is 174.0 (1)° and this nearly linear arrangement is consistent with a tetrel bond formed via a σ-hole opposite the tin-chlorine covalent bond. Some weak C-H⋯Cl inter-actions are noted between adjacent mol-ecules.
