ABSTRACT
In the mol-ecule of the title compound, C22H14Cl4N4, the central benzene ring makes dihedral angles of 77.03â (9) and 81.42â (9)° with the two approximately planar 2,2-di-chloro-1-[(E)-phenyl-diazen-yl]vinyl groups. In the crystal, mol-ecules are linked by C-Hâ¯π, C-Clâ¯π, Clâ¯Cl and Clâ¯H inter-actions, forming a three-dimensional network. The Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from Hâ¯H (30.4%), Câ¯H/Hâ¯C (20.4%), Clâ¯H/Hâ¯Cl (19.4%), Clâ¯Cl (7.8%) and Clâ¯C/Câ¯Cl (7.3%) inter-actions.
