Crystal structure of 2-{5-[2-(2-hy-droxy-phen-yl)diazen-1-yl]-1-methyl-pyrrol-2-yl}phenol methanol monosolvate.

In the title azo-pyrrole compound, C(17)H(15)N(3)O(2)·CH(3)OH, the azo N=N bond adopts a trans configuration 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 supra-molecular ring structure is formed between two azo-pyrrole and two methanol solvent mol-ecules through four O-H⋯O hydrogen bonds.
