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

Abstract

In the title compound, C13H13N3O, 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 linkedviaN—H...O hydrogen bonds involving the central –NHC(=O)NH– units, forming chains running parallel to thebaxis. These chains associate with one anotherviaN—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.
