Crystal structure of catena-poly[[tri­methyl­tin(IV)]-μ-2-(2-nitro­phen­yl)acetato-κ(2) O:O′]

In the title one-dimensional coordination polymer, [Sn(CH(3))(3)(C(8)H(6)NO(4))](n), the Sn(IV) atom is coordinated by three methyl C atoms and two carboxyl­ate O atoms (one symmetry generated), resulting in an almost regular SnC(3)O(2) trigonal pyramid. The C atoms occupy the equatorial sites and the O atoms occupy the axial sites. In the ligand, the dihedral angles between the benzene ring and the pendant acetate and nitro groups are 57.7 (1) and 36.9 (3)°, respectively. The bridging ligand leads to [010] chains in the crystal, with adjacent metal atoms related by a 2(1) screw axis. A weak π–π inter­action exists between the centroids of symmetry-related benzene rings at a distance of 3.9131 (19) Å.
