Abstract: The title compound, C₁₃H₉F₃N₂O₂S, crystallizes with two independent molecules in the asymmetric unit. The central thiourea core is roughly coplanar with the furan and benzene rings, showing O-C-N-C(S) torsion angles of 2.3 (4) and -11.4 (2)° and (S)C-N-C-C torsion angles of -2.4 (4) and -28.8 (4)°, respectively, in the two independent molecules. The trans-cis geometry of the thiourea fragment is stabilized by an intramolecular N-HO hydrogen bond between the H atom of the cis thioamide and the carbonyl O atom. In the crystal structure, intermolecular N-HS hydrogen bonds form centrosymmetric dimers extending along the b axis.
