Abstract: 1 (No. 2) with two independent mol-ecules in the asymmetric unit. The mol-ecular structure was analyzed using spectroscopic and crystallographic techniques, confirming the expected configuration and electronic environment. Hirshfeld surface analysis revealed key non-covalent inter-actions such as C-H⋯π, C-H⋯Br, π-π stacking, and halogen bonding, which consolidate the crystal structure. The study provides valuable insights into the structural features and inter-molecular inter-actions of this brominated azo compound, which may have potential applications in optoelectronic materials, dyes, and mol-ecular switches.
