Crystal structure of 1-(2-amino­phen­yl)-3-phenyl­urea

In the title compound, C(13)H(13)N(3)O, the phenyl ring makes a dihedral angle of 47.0 (1)° with the mean plane of the –NC(=O)N– unit, while the dihedral angle between the latter mean plane and the amino­phenyl ring is 84.43 (7)°. In the crystal, mol­ecules are linked via N—H⋯O hydrogen bonds involving the central –NHC(=O)NH– units, forming chains running parallel to the b axis. These chains associate with one another via N—H⋯O and N—H⋯N hydrogen bonds, from the pendant amino groups to the –NHC(=O)NH– units of adjacent mol­ecules, forming columns propagating along [010]. The structure was refined as a two-component twin with a 0.933 (3):0.067 (3) domain ratio.
