title: 2-{2-[2-(1,3-Dioxoisoindol-2-yl)eth-oxy]eth-yl}isoindole-1,3-dione.
abstract: In the mol-ecule of the title compound, C(20)H(16)N(2)O(5), the phthalimide fragments are almost planar, with r.m.s. deviations of 0.018 and 0.020 Å, and make a dihedral angle of 53.64 (3)°. The mol-ecular and crystal structures are stabilized by a weak inter-molecular C-H⋯O, C-H⋯π and C=O⋯π [2.883 (1) Å] inter-actions and aromatic π-π stacking inter-actions with a centroid-centroid distance of 3.6189 (7) Å.
