Abstract: The crystal structure of the title compound, [Sn(C₄H₉)₂(C₁₅H₉Cl₂O₂)₂], has a highly distorted octahedral geometry that may be best described as a skew-trapezoid planar geometry with two additional axial ligands. The carboxylate ligands are asymmetrically coordinated to the Sn atoms, with short Sn-O covalent bonds [mean 2.098  (6)  Å] and long dative bonds [mean 2.602  (12)  Å]. The mean Sn-C distance for the n-butyl groups is 2.117  (13)  Å, with a C-Sn-C angle of 139.18  (18)°.
