Abstract

In he title compound, C16H13Br4N, the carbazole skeleton is nearly planar [maximum deviation = 0.026 (4) Å] and makes a dihedral angle of 73.8 (4)° with the butyl chain. The butyl chain adopts a trans conformation. In the crystal, mol­ecules are linked by π–π stacking inter­actions [centroid–centroid distance = 3.559 (2) Å].
