Abstract: The title compound, [Sn(C₄H₉)₃(C₇H₉O₂)]_n, forms a polymeric chain involving both O atoms of the carboxylate group. The Sn atom is five-coordinate and shows a distorted trigonal-bipyramidal geometry wherein the C atoms of the n-butyl chains occupy the equatorial positions. Two O atoms from symmetry-related ligands are asymmetrically bonded to the Sn atom and occupy axial positions with significantly different Sn-O distances of 2.209 (2) and 2.358 (2) Å.
