The two pyrrole rings are essentially planar (r.m.s. deviation = 0.002 A˚ ) and they form a dihedral angle of 81.24 (10) with each other. The crystal packing is stabilized by C—H interactions and – stacking interactions, forming a three-dimensional network. The Hirshfeld surface analysis and two-dimensional fingerprint plots reveal that the most important contributions for the crystal packing are from H
