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, C16H14Cl2N2O, 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 and van der Waals interactions. The title compound was refined as a two-component nonmerohedral twin, BASF 0.1076 (5). The Hirshfeld surface analysis and twodimensional 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.
