Abstract
In the title compound, C16H13Cl4N3, the dihedral angle between the benzene rings of the dichlorophenyl and dimethylaniline groups is 50.85 (13)°. The central –N=N– unit shows an E configuration. In the crystal, molecules form parallel layers to the (100) plane by C—H···π and face-to-face π-π [centroid-to-centroid distances = 4.0538 (17) and 4.0537 (17) Å] interactions. These layers are connected by Van der Waals interactions to stabilize the crystal structure. Hirshfeld surface analysis indicates that the most important contributions for the crystal packing are from Cl···H/H···Cl (36.4%), H···H (23.3%) and C···H/H···C (15.2%) contacts.
