The mol-ecule of the title compound, C(31)H(29)N(3), contains a hexyl chain, a coordination unit (benzimidazole) and a functional group (carbazole). The benzimidazole ring is not coplanar with either the phenyl ring or the carbazole system, making dihedral angles of 43.26 (3) and 39.03 (2)°, respectively. The dihedral angle between the phenyl ring and the carbazole system is 24.42 (3)°. The hexyl C(β) atom (with respect to benzimidazole) deviates by 1.124 (2) Å from the benzimidazole plane, although the C(α) atom lies in the plane. The hexyl C(β) atom (with respect to carbazole) deviates by 1.315 (1) Å from the carbazole plane, although the C(α) atom lies in the plane. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions.
