4-[2-Methyl-4-(4-methylphenyldiazenyl)phenoxy]phthalonitrile

Abstract

The title compound, C22H16N4O, displays a trans configuration with respect to the –N=N– double bond, as found for other diazene derivatives. There is a weak intra­molecular C—H⋯N hydrogen bond, which seems to have an effect on the mol­ecular conformation. The crystal packing is governed by weak inter­molecular C—H⋯N and C—H⋯O hydrogen bonds, and weak C—H⋯π stacking.
