Abstract: In the title compound, C₁₃H₁₃NO₄, the cyclohexene ring has a sofa conformation, with the atom in position 5 of the cyclohex-2-en-1-one moiety displaced by 0.5699 (4) Å from the mean plane of the remaining atoms of the ring. A strong O-HO hydrogen bond links the molecules into infinite chains running along the b axis of the crystal. Two weak C-HO interactions involving CH groups of the aromatic ring and O atoms of the nitro or hydroxy group provide further intermolecular links, thus ensuring the formation of a three-dimensional framework in the crystal structure.
