Crystal structure of (S)-4-carbamoyl-4-(1,3-dioxoisoindolin-2-yl)butanoic acid

Abstract

In the title compound, C13H12N2O5, the phthalimide ring system is essentially planar, with a maximum deviation of 0.0479 (14) Å. In the crystal, each molecule is linked via six neighbouring molecules into a three-dimensional network through N—H...O and O—H...O hydrogen bonds, which form an R32(8) ring motif.
