Crystal structure and Hirshfeld surface analysis of ( <i>E</i> )-1-{2,2-dibromo-1-[4-( <i>tert</i> -butyl)phenyl]ethenyl}-2-(3,4-dimethylphenyl)diazene
The title azo compound, C<sub>20</sub>H<sub>22</sub>Br<sub>2</sub>N<sub>2</sub>, crystallizes in the triclinic space group <i>P</i>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.
