The single-crystal X-ray diffraction structure of the title compound, [SnCl(CH)]·CHOP, 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 a σ-hole opposite the tin-chlorine covalent bond. Some weak C-H⋯Cl inter-actions are noted between adjacent mol-ecules.
报道了标题化合物[SnCl(CH)]·CHOP的单晶X射线衍射结构。该1:1共晶体在锡和氧之间具有短程且定向的碳族元素键。锡-氧距离为2.346(4) Å，占锡和氧范德华半径之和的62%。Cl-Sn⋯O角为174.0(1)°，这种近乎线性的排列与在锡-氯共价键对面形成σ-空穴而形成的碳族元素键一致。在相邻分子之间注意到一些弱的C-H⋯Cl相互作用。
