Abstract: The asymmetric unit of the title compound, C₇H₆F₂N₂S, consists of two independent molecules, with comparable geometries. In one molecule, the thiourea moiety is essentially planar (r.m.s. deviation = 0.014 Å) and it forms a dihedral angle of 78.67 (9)° with the benzene ring. The corresponding r.m.s. deviation and dihedral angle for the other molecule are 0.011 Å and 81.71 (8)°, respectively. In both molecules, one of the F atoms is disordered over two positions with refined site occupancies of 0.572 (3):0.428 (3) and 0.909 (2):0.091 (2), respectively. In the crystal, molecules are linked via N-HS and C-HF hydrogen bonds into two-dimensional networks parallel to (010).
