A 1:2 complex of pyromellitic diimide and dimethyl sulfoxide

A. D. Bond

Abstract: Recrystallization of pyromellitic diimide from dimethyl sulfoxide yields a 1:2 complex, C₁₀H₄N₂O₄·2C₂H₆SO. In space group P2₁/c, the diimide molecules form herring-bone-packed layers and are capped at each end by hydrogen-bonded dimethyl sulfoxide molecules. The 1:2 complex is sited on a crystallographic centre of symmetry.
