N,N′-Bis(4-fluoro­phen­yl)urea

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-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 i...

Sumario: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-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.
