4-[(4-Chlorophenyl)diazenyl]-3-methoxyaniline

Abstract

The title compound, C13H12ClN3O, exhibits a trans geometry about the N=N double bond in the solid state. The dihedral angle between the rings is 22.20 (8)°. Intermolecular N—H...O hydrogen bonds between the amine and methoxy groups lead to the formation of a chain-like polymer along the c axis with a C(6) graph set. There is also weak non-classical C—H...N hydrogen bonds involving an aromatic C—H group and a diazenyl N atom, which connect the chains into a two-dimensional framework.
