Crystal structure of 1-benzoyl-3-(4-fluoro­phen­yl)thio­urea

The title compound, C₁₄H₁₁FN₂OS, contains two mol­ecules (A and B) in the asymmetric unit, with different conformations. In mol­ecule A, the dihedral angles between the central thio­urea grouping and the phenyl and fluoro­benzene rings are 28.77 (8) and 41.82 (8)°, respectively, and the dihedral angle between the ring planes is 70.02 (9)°. Equivalent data for mol­ecule B are 8.46 (8), 47.78 (8) and 52.99 (9)°, respectively. Both mol­ecules feature an intra­molecular N—H...O hydrogen bond, which closes an S(6) ring. In the crystal, A+B dimers linked by pairs of N—H...S hydrogen bonds generate R₂²(8) loops.
