Crystal structure and Hirshfeld surface analysis of (E)-1-[2,2-di­chloro-1-(4-methyl­phen­yl)ethen­yl]-2-(4-meth­oxy­phen­yl)diazene

The asymmetric unit of the title compound, C(16)H(14)Cl(2)N(2)O, comprises two similar mol­ecules, A and B, in which the dihedral angles between the two aromatic rings are 70.1 (3) and 73.2 (2)°, respectively. The crystal structure features short C—H⋯Cl and C—H⋯O contacts and C—H⋯π and van der Waals inter­actions. The title compound was refined as a two-component non-merohedral twin, BASF 0.1076 (5). The Hirshfeld surface analysis and two-dimensional fingerprint plots show that H⋯H (38.2% for mol­ecule A; 36.0% for mol­ecule B), Cl⋯H/H⋯Cl (24.6% for mol­ecule A; 26.7% for mol­ecule B) and C⋯H/H⋯C (20.0% for mol­ecule A; 20.2% for mol­ecule B) inter­actions are the most important contributors to the crystal packing.
