Abstract
In the title compound, C11H7F3N2O4S2, the 1,3-thiazol-2-amine residue is almost perpendicular to the central benzene ring [dihedral angle = 84.3 (2) degrees]. There is a small twist between the benzene ring and the ester group [C-O-C-C torsion angle = 9.8 (6)degrees]. Thus, the molecule has an L-shape. Inversion-related dimers are connected in the crystal packing by pairs of N-H center dot center dot center dot N hydrogen bonds formed between the amine H and thiazole N atom via eight- membered {center dot center dot center dot HNCN}(2) synthons.
