catena-Poly[[tribenzyl-tin(IV)]-μ-(E)-3-(2-fur-yl)prop-2-enoato-κO:O']

In the title carboxyl-ate-bridged polymer, [Sn(C(7)H(7))(3)(C(7)H(5)O(3))](n), the Sn(IV) atom exists in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry. The polymer propagates as a chain along the a axis. There are two independent formula units in the asymmetric unit; the furyl ring of one of the anions is disordered over two positions in a 0.630 (8):0.370 (8) ratio. The crystal studied was a non-merohedral twin with a minor twin domain of 37.3 (1)%.
