Bis[2-(1,3-dioxoisoindolin-2-yl)ethyl] phthalate

Abstract

The title compound, C28H20N2O8, was synthesized by the reaction of isobenzofuran-1,3-dione and 2-aminoethanol in a one-pot reaction. The benzene and five-membered rings are slightly twisted to each other, making dihedral angles of 2.77 (9) and 1.77 (10)°. The rings of the phthalimide groups make dihedral angle of 57.64 (7) and 83.46 (7)° with the central benzene ring. Weak C—H...O, C—H...π and π–π [centroid–centroid distance = 3.446 (1) and 3.599 (1) Å] interactions reinforce the cohesion of the crystal.
