Abstract
The azo N=N bond adopts a trans conformation and the pyrrole N and azo group are in an anti orientation. The dihedral angles between the pyrrole ring and the two phenyl rings are 6.7 (3) and 54.7 (3)°. In the crystal, a supramolecular ring structure is formed between two azopyrrole and two methanol solvent molecules through four O—H⋯O hydrogen bonds.
