Abstract: In the title compound, C35H32N4, the C-N bond lengths in the guanidine part are 1.286 (3), 1.387 (2) and 1.414 (2) Å, indicating double- and single-bond character. The N-C-N angles are 114.48 (17), 118.78 (17) and 126.72 (17)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. The carbazole ring system is almost planar (r.m.s. deviation = 0.002 Å). In the crystal, molecules are connected by weak C-HN hydrogen bonds, generating a zigzag chain along the ac plane. Weak - interactions [centroid-centroid distance = 3.785 (1) Å] between two phenyl rings of the guanidine moiety are also present.
