N-(4-Hydroxy-2-nitrophenyl)acetamide

Abstract

The title compound, C8H8N2O4, differs in its degree of planarity from the 3-nitro isomer and also in its hydrogen-bonding pattern. Its NH group forms an intramolecular hydrogen bond to a nitro oxygen atom, and its OH group forms an intermolecular hydrogen bond to an amide oxygen atom, generating [10\overline{1}] chains in the crystal.
