In the title compound, [Sn(CH₃)₃(C₁₆H₁₃O₃)], the Sn atom has fivefold coordination involving three methyl C atoms defining the equatorial plane of a trigonal bipyramid and two O atoms from two carboxylate groups occupying the axial positions. The Sn-C bond lengths [2.106 (6), 2.110(5) and 2.116 (5) angstroms] are very similar. The two carboxylate O atoms have notably different distances to the metal atom [2.184 (3) and 2.433 (4) angstroms], with an O-Sn-O angle of 174.0(1)°. Bidentate bridging of the carboxylate ligands via trimethyltin groups forms a polymeric structure.
