Özet

© 2022 Published under a CC BY 4.0 licence.The molecule of the title compound, C14H8Br3N3O2, 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 14;(15) and 72.57 14;(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.
