2-tert-Butyl-6-[(4-chloro-2-nitrophenyl)diazenyl]-4-methylphenol

Abstract

In the title compound, C17H18ClN3O3, the dihedral angle between the planes of the two benzene rings is 1.03 (7)°. The overall conformation of the molecule is influenced, in part, by electron delocalization and by an intramolecular bifurcated O—H...(O,N) hydrogen bonds. The O atoms of the nitro group, one of which serves as an H bond acceptor, are disordered over two sets of sites with refined occupancies of 0.56 (3) and 0.44 (3).
