2-[4-(Carbazol-9-yl)phen­yl]-1,3-diethyl-1,3-di­phenyl­guanidine

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—H...N hydrogen bonds, generating a zigzag chain along the ac plane. Weak π–π inter­actions [centroid–centroid distance = 3.785 (1) Å] between two phenyl rings of the guanidine moiety are also present.
