Crystal structure and Hirshfeld surface analysis of (<i>E</i>)-4-{2,2-dichloro-1-[(3,5-dimethylphenyl)diazenyl]ethenyl}-<i>N</i>,<i>N</i>-dimethylaniline

Abstract

In the title compound, C₁₈H₁₉Cl₂N₃, the planes of the benzene rings subtend a dihedral angle of 77.07 (10)°. In the crystal, mol-ecules are associated into inversion dimers <i>via</i> short Cl⋯Cl contacts [3.3763 (9) Å]. A Hirshfeld surface analysis indicates that the most important contact percentages for the different types of inter-actions are H⋯H (43.9%), Cl⋯H/H⋯Cl (22.9%), C⋯H/H⋯C (20.8%) and N⋯H/H⋯N (8.0%).
