In the centrosymmetric tetra­nuclear title compound, [Sn4(C4H9)8(C7H5O3)4O2], one of the two independent Sn atoms is five-coordinate in a cis-C2SnO3 trigonal-bipyramidal geometry [C—Sn—C = 142.7 (1)°]; the geometry is distorted owing to a long Sn⋯O(double bond) inter­action [Sn⋯O = 2.862 (1) Å]. The other Sn atom has a bent R 2Sn skeleton [C—Sn—C = 144.0 (1)°], but the geometry is best regarded as being a trans-C2SnO4 octa­hedron as the Sn–O(single bond) inter­action is shorter [Sn—O = 2.674 (1) Å].
