Crystal structure of 2-{5-[2-(2-hydroxyphenyl)diazen-1-yl]-1-methylpyrrol-2-yl}phenol methanol monosolvate

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.
