Crystal structure and Hirshfeld surface analysis of (E)-2-(4-bromo­phen­yl)-1-[2,2-di­bromo-1-(4-nitro­phen­yl)ethen­yl]diazene

The mol­ecule of the title compound, C(14)H(8)Br(3)N(3)O(2), consists of three almost planar groups: the central di­bromo­ethenyldiazene fragment and two attached aromatic rings. The mean planes of these rings form dihedral angles with the plane of the central fragment of 26.35 (15) and 72.57 (14)° for bromine- and nitro-substituted rings, respectively. In the crystal, C—H⋯Br inter­actions connect mol­ecules, generating zigzag C(8) chains along the [100] direction. These chains are linked by C—Br⋯π inter­actions into layers parallel to (001). van der Waals inter­actions between the layers aid in the cohesion of the crystal packing. The most substantial contributions to crystal packing, according to a Hirshfeld surface analysis, are from Br⋯H/H⋯Br (20.9%), C⋯H/H⋯C (15.2%), O⋯H/H⋯O (12.6%) and H⋯H (11.7%) contacts.
