Abstract
The asymmetric unit of the title compound, C13H10F2N2O, contains one and a half N,N′-bis(4-fluorophenyl)urea molecules. One of the molecules has crystallographic twofold rotation symmetry. The benzene rings are twisted from each other by dihedral angles of 29.69 (6)° for the molecule in a general position and 89.83 (6)° for the symmetry-generated molecule. In the crystal structure, a pair of intermolecular N—H⋯O hydrogen bonds link symmetry-related molecules into chains along the b axis, forming R 2 1(6) ring motifs.
