Abstract: There are two independent and conformationally dissimilar molecules (A and B) in the asymmetric unit of the title compound, C11H6F3N3O3S; the dihedral angles between the benzene and thiazole rings are 33.8 (2)° in A and 59.7 (2)° in B. The similarity of the C-N bond lengths in the amide group [1.379 (5) and 1.358 (5) Å for A, and 1.365 (5) and 1.363 (5) Å for B] indicates the presence of conjugation between the two rings. In the crystal, molecules are linked by N-HN hydrogen bonds, forming chains extending along ; weak N-HOamide interactions are also present in the structure.
