Crystal structure of catena-poly[[tri-methyl-tin(IV)]-μ-2-(2-nitro-phen-yl)acetato-κ(2) O:O'].

ABSTRACT: In the title one-dimensional coordination polymer, [Sn(CH3)3(C8H6NO4)] n , the Sn(IV) atom is coordinated by three methyl C atoms and two carboxyl-ate O atoms (one symmetry generated), resulting in an almost regular SnC3O2 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 21 screw axis. A weak π-π inter-action exists between the centroids of symmetry-related benzene rings at a distance of 3.9131 (19) Å.
