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.
标题化合物[Sn(C₆H₅)₃(C₇H₅N₂O₄)]的不对称单元由两个独立分子组成。在每个分子中，四配位的Sn(IV)原子呈扭曲的四面体几何构型，并且存在两个具有S(6)环模式的分子内N-H⋯O氢键。在一个分子中，2-氨基-3-硝基苯甲酸酯配体的苯环与三个苯环形成的二面角分别为42.74 (11)°、89.66 (13)°和53.04 (10)°。另一个分子的相应二面角为6.29 (11)°、66.55 (11)°和62.33 (10)°。在晶体中，观察到一个弱的分子间C-H⋯π相互作用和一个质心-质心距离为3.5877 (12) Å的π-π堆积相互作用。
