2-(2-Hydroxyethyl)-3-[(2-hydroxyethyl)imino]isoindolin-1-one

In the crystal structure of the title compound, C12H14N2O3, molecules are packed into layers parallel to (100). Each layer contains centrosymmetric dimers formed by a pair of strong O—H...N hydrogen bonds with an R22(10) motif, while strong O—H...O hydrogen bonds forming C(10) chains connect molecules into a two-dimensional network. Additional stabilization is supplied by weak C—H...O hydrogen bonds and weak π–π stacking interactions with centroid–centroid distances in the range 3.4220 (7)–3.9616 (7) .
