2-(3-Oxocyclohex-1-enylamino)acetic acid

Abstract

The six-membered ring of the title compound, C8H11NO3, adopts an envelope shape with the C atom in the meta position of the carbonyl representing the flap. This atom is disordered over two positions in an 0.865 (6): 0.135 (6) ratio. In the crystal, a two-dimensional supramolecular network parallel to the ac plane is built up from O—H...O and N—H...O hydrogen bonds.
