In the title compound, C(11)H(7)F(3)N(2)O(4)S(2), the 1,3-thia-zol-2-amine residue is almost perpendicular to the central benzene ring [dihedral angle = 84.3 (2)°]. There is a small twist between the benzene ring and the ester group [C-O-C-C torsion angle = 9.8 (6)°]. Thus, the mol-ecule has an L-shape. Inversion-related dimers are connected in the crystal packing by pairs of N-H⋯N hydrogen bonds formed between the amine H and thia-zole N atom via eight-membered {⋯HNCN}(2) synthons.
在标题化合物C₁₁H₇F₃N₂O₄S₂中，1,3 - 噻唑 - 2 - 胺残基几乎垂直于中心苯环[二面角 = 84.3 (2)°]。苯环与酯基之间存在小的扭转[C - O - C - C扭转角 = 9.8 (6)°]。因此，分子呈L形。在晶体堆积中，通过胺H与噻唑N原子之间形成的N - H⋯N氢键对，经由八元{⋯HNCN}(2) 合成子连接了与反演相关的二聚体。
