Crystal structure of 4-bromo-N-[(3,6-di-tert-butyl-9H-carbazol-1-yl)methylidene]aniline
2019
In the title compound, C27H29BrN2, the carbazole ring system is essentially planar, with an r.m.s. deviation of 0.0781 (16) A. An intramolecular N—H⋯N hydrogen bond forms an S(6) ring motif. One of the tert-butyl substituents shows rotational disorder over two sites with occupancies of 0.592 (3) and 0.408 (3). In the crystal, two molecules are associated into an inversion dimer through a pair of C—H⋯π interactions. The dimers are further linked by another pair of C—H⋯π interactions, forming a ribbon along the c-axis direction. A C—H⋯π interaction involving the minor disordered component and the carbazole ring system links the ribbons, generating a network sheet parallel to (100).
