title: catena-Poly[[tribenzyl-tin(IV)]-μ-4-nitro-cinnamato-κO:O'].
abstract: The 4-nitro-cinnamate anion in the title compound, [Sn(C(7)H(7))(3)(C(9)H(6)NO(4))](n), bridges adjacent tribenzyl-tin cations into a helical chain running along the b axis. The Sn atoms in the two independent mol-ecules adopt distorted trans-C(3)SnO(2) trigonal-bipyramidal geometries. The repeat distance of the polymeric chain is b/2.
