N,N-Dimethyl-4-[(E)-2-(3,6,7-tribromo-9-butyl-9H-carbazol-2-yl)ethen-yl] aniline

Abstract

In the title mol-ecule, C26H25Br3N 2, a dihedral angle of 6.15 (10)° is present between the carbazole and benzene ring systems with an E conformation about the C=C bond [1.335 (4) Å]. The butyl group is almost perpendicular to the carbazole plane [C-N-C-C torsion angle =-98.7 (3)°]. In the crystal, supra-molecular double chains along [-7,18,-16] are formed via C-H⋯Br and π-π inter-actions [centroid(carbazole five-membered ring)⋯centroid(carbazole six-membered ring) distance = 3.6333 (13) Å].
