catena-Poly[[tribenzyl-tin(IV)]-μ-4-formyl-2-meth-oxy-6-nitro-phenolato-κO:O]

The formyl-meth-oxy-nitro-phenoxide ions in the polymeric title compound, [Sn(C(7)H(7))(3)(C(8)H(6)NO(5))](n), link adjacent triorganotin(IV) cations into linear chains lying close to (101) [Sn-O = 2.1227 (12) Å and Sn← O = 2.4936 (13) Å]. The Sn(IV) atom is displaced out of the C(3)Sn girdle of the trans-C(3)SnO(2) trigonal-bipyramidal polyhedron in the direction of the covalently-bonded O atom [Sn-O-C = 137.63 (11)°] by 0.247 (1) Å; the geometry is distorted towards an octa-hedron by a remote O atom of the meth-oxy subsituent [Sn⋯O = 3.019 (1) Å].
