4-(4-Hydroxyphenyldiazenyl)benzonitrile

C. Z. Zhang

Abstract: The molecule of the title compound, C₁₃H₉N₃O, is achiral but forms a chiral arrangement in the crystal structure. The molecule adopts an E configuration with respect to the N=N bond and is almost planar, with an r.m.s. deviation of 0.0439 Å from the plane through all atoms in the molecule. The dihedral angle between the two benzene rings is 2.2 (2)°. In the crystal structure, intermolecular O-HN hydrogen bonding generates a chain.
