Abstract
In the title compound, C26H16N6O, the dihedral angles between the central pyrrole ring and the pendant indole ring system (r.m.s. deviation = 0.027 Å) and the azide-bearing benzene ring are 37.56 (8) and 51.62 (11)°, respectively. The azide group is almost coplanar with its attached benzene ring [C—C—N—N = 3.8 (3)°]. The benzoyl benzene ring is disordered over two orientations twisted with respect to each other by 9.29 (8)° in a 0.514 (2):0.486 (2) ratio. In the crystal, inversion dimers linked by pairs of Np—H⋯O (p = pyrrole) hydrogen bonds generate R 2 2(10) loops. A second inversion dimer arises from a pair of Ni—H⋯Nc (i = indole and c = cyanide) hydrogen bonds, which generates an R 2 2(16) loop. Together, the hydrogen bonds lead to [011] chains in the crystal.
