4-[(4-Chloro-phen-yl)diazen-yl]-3-meth-oxy-aniline

Abstract

The title compound, C 13H 12ClN 3O, exhibits a trans geometry about the N=N double bond in the solid state. The dihedral angle between the rings is 22.20 (8)°. Inter-molecular N - H⋯O hydrogen bonds between the amine and meth-oxy 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. © Rofouei et al. 2011.
