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 42.74 (11), 89.66 (13) and 53.04 (10)° with the three phenyl rings. The corresponding dihedral angles for the other mol-ecule are 6.29 (11), 66.55 (11) and 62.33 (10)°. In the crystal, a weak inter-molecular C-H⋯π inter-action and a π-π stacking inter-action with a centroid-centroid distance of 3.5877 (12) Å are observed.
