exo,exo-4-(2-Hydroxyethyl)-10-oxa-4-azatricyclo[5.2.1.02,6]dec-8-ene-3,5-dione

In the crystal of the title compound, C10H11NO4, the hydroxy group forms an O—H⋯Ocarbonyl hydrogen bond with an adjacent molecule, so forming chains which extend along (010). Further weak C—H⋯O hydrogen-bonding associations give an infinite three-dimensional network structure.
