In the title compound, [Sn(C15H14NO2)(CH3)3], the Sn atom has a distorted trigonal bipyramidal coordination. The three bonds to methyl groups in the equatorial plane have almost the same values [Sn—C range 2.106 (3)–2.113 (4) Å], but the Sn—O bonds in the axial positions involving one carboxyl O atom [Sn1—O1 2.153 (2) Å] and another symmetry-related carboxyl O atom in the trans position [Sn1—O2 2.495 (2) Å] have quite different values. The angle O1—Sn1—O2 is 173.60 (8)°. Each trimethyltin group bridges two neighbouring 2-[(2,3-dimethylphenyl)amino]benzoate ligands via carboxyl moities to form polymeric chains.
