| Zusammenfassung: | <jats:p>The title chiral photochromic Schiff base compound, C<jats:sub>21</jats:sub>H<jats:sub>18</jats:sub>BrN<jats:sub>3</jats:sub>O, was synthesized from (<jats:italic>R</jats:italic>)-(+)-1-(4-bromophenyl)ethylamine and the salicylaldehyde of an azobenzene derivative. The molecule corresponds to the phenol–imine tautomer, the C=N and N—C bond distances being 1.285 (3) and 1.470 (3) Å, respectively. The diazenyl group adopts a<jats:italic>trans</jats:italic>form, with an N=N distance of 1.256 (3) Å. The hydroxy group is involved in intramolecular O—H...N hydrogen bonding. In the crystal, C—H...π interactions consolidate the crystal packing of one-dimensional chains, which exhibits short intermolecular Br...C contacts of 3.400 (3) Å.</jats:p> |
