The title compound, C33H33N3, is a carbazolophane, which is a cyclophane composed of two carbazole fragments. It has a planar chirality but crystallizes as a racemate in the space group P. The molecule adopts an anti-configuration, in which two carbazole fragments are partially overlapped. Both carbazole ring systems are slightly bent, with the C atoms at 3-positions showing the largest deviations from the mean planes. The dihedral angle between two carbazole fragments is 5.19 14;(3)°, allowing an intramolecular slipped π-π interaction [Cg⋯Cg = 3.2514 14;(8) 14;Å]. In the crystal, the molecules are linked via intermolecular C - H⋯N hydrogen bonds and C - H⋯π interactions into a network sheet parallel to the ab plane. The molecules of different sheets form other C - H⋯π interactions, thus forming a three-dimensional network.
