2:1 Complex of 3-Picoline N-Oxide and Hydroquinone

The title system, 2C₆H₇NO.C₆H₆O₂, belongs to a series of molecular complexes formed from 3-picoline N-oxide and diverse hydrogen-bond donors. The molecular complex owes its formation to a hydrogen-bond between the O atom of the N-oxide group of each 3-picoline N-oxide molecule and the O atom of an OH group of the hydroquinone molecule. The complex has a dihedral angle 48.16 (5)° between the aromatic rings and exhibits an overlap between the hydroquinone and 3-picoline N-oxide molecules in the [001] direction. Its structural characteristics are compared to those of similar systems.
