catena-Poly[[tribenzyl-tin(IV)]-μ-2-(piperidin-1-ylcarbothio-ylsulfan-yl)acetato-κO:O'].

The Sn atom in the title polymeric compound, [Sn(C(7)H(7))(3)(C(8)H(12)NO(2)S(2))](n), exists in a trans-C(3)O(2) trigonal-bipyramidal coordination environment in the two independent formula units. The carboxyl-ate moiety functions in a bridging mode, linking adjacent triorganotin cations into a linear chain running along the shortest axis of the triclinic unit cell; the repeat distance of the polymer is half the a-axial length. In one formula unit, the Sn atom is displaced out of the equatorial plane in the direction of the Sn-O(covalent) bond by 0.093 (4) Å and in the second mol-ecule, the Sn atom is displaced by 0.105 (4) Å in the same direction.
