(2-Amino-3-nitro-benzoato-κO)triphenyl-tin(IV).

The asymmetric unit of the title compound, [Sn(C(6)H(5))(3)(C(7)H(5)N(2)O(4))], consists of two independent mol-ecules. In each mol-ecule, the four-coordinated Sn(IV) atom exists in a distorted tetra-hedral geometry and two intra-molecular N-H⋯O hydrogen bonds with S(6) ring motifs are present. In one mol-ecule, the benzene ring of the 2-amino-3-nitro-benzoate ligand makes dihedral angles of 42.
