title: 3-Methyl-4-nitro-phenol-4-dimethyl-amino-pyridine (1/1).
abstract: In the title adduct, C(7)H(7)NO(3) (.)C(7)H(10)N(2), the dihedral angle betwen the benzene ring and pyridine rings is 9.60 (8)° while the nitro group attached to the benzene ring makes a dihedral angle of 21.76 (13)°. The hydroxyl O atom deviates by 0.0247 (15) Å from the plane of the benzene ring. The crystal packing features O-H⋯N hydrogen bonds.
