In the mol-ecule of the title compound, [Sn(C(2)H(5))(2)(C(10)H(8)ClO(2))(2)], the Sn atom is six-coordinated in a distorted tetra-gonal-bipyramidal configuration by four O atoms in the equatorial plane and two C atoms in the axial positions. Intra-molecular C-H⋯O hydrogen bonds result in the formation of two planar and two non-planar five-membered rings; the latter adopt envelope conformations. There are weak π-π inter-actions between aromatic rings, with centroid-to-centroid distances of 3.796 (2) and 4.171 (2) Å. There is also a single C-Cl⋯π inter-action [C-Cl = 1.740 (4), Cl⋯π = 3.795 (2) C⋯π = 3.697 (4) Åand C-Cl⋯\p =73.45 (11)°].
在标题化合物[Sn(C₂H₅)₂(C₁₀H₈ClO₂)₂]的分子中,Sn原子通过赤道平面上的四个O原子和轴向位置的两个C原子以扭曲的四方双锥构型进行六配位。分子内的C—H⋯O氢键导致形成两个平面和两个非平面的五元环;后者采用信封构象。芳环之间存在弱的π-π相互作用,质心到质心的距离为3.796 (2) 和4.171 (2) Å。还存在单个C-Cl⋯π相互作用[C-Cl = 1.740 (4),Cl⋯π = 3.795 (2),C⋯π = 3.697 (4) Å 且 C-Cl⋯π = 73.45 (11)°]。
