2-{2-[2-(1,3-Dioxoisoindol-2-yl)ethoxy]ethyl}isoindole-1,3-dione

Abstract

In the molecule of the title compound, C20H16N2O5, 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 molecular and crystal structures are stabilized by a weak intermolecular C—H...O, C—H...π and C=O...π [2.883 (1) Å] interactions and aromatic π–π stacking interactions with a centroid–centroid distance of 3.6189 (7) Å.
