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, C 18 H 19 Cl 2 N 3 , the planes of the benzene rings subtend a dihedral angle of 77.07 (10)°. In the crystal, molecules are associated into inversion dimers via short Cl...Cl contacts [3.3763 (9) Å]. A Hirshfeld surface analysis indicates that the most important contact percentages for the different types of interactions are H...H (43.9%), Cl...H/H...Cl (22.9%), C...H/H...C (20.8%) and N...H/H...N (8.0%).
