The complete molecule of the title compound, C22H 16N2O4, is generated by a crystallographic centre of inversion. The plane of the central aromatic ring is tilted by 11.85 (4)° with respect to the outer aromatic ring. The crystal packing is determined by van der Waals inter-actions, with stair-like stacking between adjacent aromatic rings. The stacks are staggered and each layer is approximately 3.8 Å from the next. The closest inter-molecular contact (approximately 2.42 Å) is between an O atom and a vinyl H atom.
