9,9′-(Biphenyl-2,2′-diyl)difluoren-9-ol 4-methylpyridine solvate

Abstract

The title compound, C38H26O2·C6H7N, crystallized as a host–guest complex from a solvent mixture of 4-methyl­pyridine and acetone. The dihedral angle between the rings in the biphenyl unit is 87.06 (3)°. The methyl­pyridine guest mol­ecules are linked to the host mol­ecules via O—H⋯ N hydrogen bonds, forming discrete pairs. The other OH group of the host forms an intra­molecular O—H⋯O hydrogen bond.
