چکیده
The asymmetric unit of the title compound, C(13)H(10)F(2)N(2)O, contains one and a half N,N'-bis-(4-fluoro-phen-yl)urea mol-ecules. One of the mol-ecules has crystallographic twofold rotation symmetry. The benzene rings are twisted from each other by dihedral angles of 29.69 (6)° for the mol-ecule in a general position and 89.83 (6)° for the symmetry-generated mol-ecule. In the crystal structure, a pair of inter-molecular N-H⋯O hydrogen bonds link symmetry-related mol-ecules into chains along the b axis, forming R(2) (1)(6) ring motifs.
