The title compound, C(11)H(9)NO(5), was prepared by the reaction of 2-furan-acrylic acid and N-hy-droxy-succinimide. The mol-ecule consists of two approximately planar moieties, viz. a succinimide group and the rest of the mol-ecule [the largest deviations from the least-squares planes are 0.120 (1) and 0.210 (1) Å, respectively]. The dihedral angle between these fragments is 63.70 (5)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds into two-dimensional nets.
