catena-Poly[tributyl­tin(IV)-μ-acetato]

The title compound, [Sn(C₄H₉)₃(C₂H₃O₂)]_n, forms characteristic polymeric chains, in which Sn atoms are bridged by acetate groups, bonding through both O atoms. The coordin­ation geometry of the Sn atom is slightly distorted trigonal bipyramidal. The butyl groups occupy the equatorial positions, with Sn—C bond lengths in the range 2.115 (10)–2.129 (9) Å, while the axial Sn—O bond lengths are 2.178 (5) and 2.422 (5) Å.
