N,N′-diphenylperylene-3,4:9,10-bis(dicarboximide)

The title compound, C36H18N2O4, has one half-molecule in the asymmetric unit with the other half generated by a crystallographic inversion centre. The perylene-imide skeleton is entirely planar, but the terminal benzene rings are twisted in the same directions by 55.55 (8)degrees. The molecules are stacked along the b axis.
