catena-Poly[[triphenyl-tin(IV)]-μ-5-amino-2-nitro-benzoato-κO:O]
Abstract:
The title compound, [Sn(C(6)H(5))(3)(C(7)H(5)N(2)O(4))](n), forms polymeric chains along [010]. The Sn(IV) ion is five-coordinated in a distorted trigonal-bipyramidal geometry by two monodentate carboxyl-ate groups and three phenyl rings. The axial sites are occupied by the O atoms of two symmetry-related carboxyl-ate groups [O-Sn-O = 170.88 (3)°]. The benzene ring of the 5-amino-2-nitro-benzoate ligand forms dihedral angles of 82.92 (6), 81.10 (6) and 83.54 (6)° with respect to the three phenyl rings. In the crystal, the chains are linked by inter-molecular N-H⋯O and weak C-H⋯O inter-actions into a three-dimensional network. The crystal structure is further stabilized by weak inter-molecular C-H⋯π inter-actions.
