In the title compound, C30H19N3O, the indole and the naphthalene ring systems are inclined to the central pyrrole ring (r.m.s. deviation = 0.012 Å) by 29.09 (9) and 49.92 (9)°, respectively. The naphthalene ring system and the indole ring are inclined to one another by 73.57 (6) and by 42.58 (10) and 74.12 (10)°, respectively, to the benzoyl ring. In the crystal, molecules are linked by pairs of Np—H...O (p = pyrrole) hydrogen bonds, forming inversion dimers withR22(10) loops. These dimers are linkedviapairs of Ni—H...Nc(i = indole and c = carbonitrile) hydrogen bonds, enclosingR22(16) loops, which leads to the formation of chains propagating in [101]. The chains are linked by C—H...π interactions, forming slabs lying parallel to (10-1).
