organic compounds
The crystal structure of the title compound (C7H7NO3) shows a strong quinoid character. The oximic function is anti with respect to the methoxy group so that no intramolecular hydrogen bonds involving the acidic H atom are formed, instead a strong intermolecular interaction is favoured. Two molecules are present in the asymmetric unit with no significative differences in their bond lengths and angles, but they do have different packing interactions.
