2,7-Dibromo-9-octyl-9H-carbazole.

ABSTRACT: In the crystal structure of the title compound, C(20)H(23)Br(2)N, the octyl chains are extended in an anti conformation and form a segregating bilayer, isolating rows of carbazole units. The carbazole moieties are engaged in offset ?-? inter-actions; the smallest centroid-to-centroid distance is 4.2822?(11)?Å. This offset packing motif allows the methyl-ene group attached directly to the N atom to be involved in two short C-H?? inter-actions (H?centroid distances = 2.96 and 2.99?Å) with an adjacent carbazole. One of the Br atoms also participates in a short contact [3.5475?(3)?Å] with a symmetry-related (-x, 1 - y, -z) Br atom. This value is significantly smaller than the sum of the van der Waals radii for bromine (3.70?Å).
