| Summary: | The title molecule, C24H14N4O2, lies on an inversion centre and the asymmetric unit containg one half-molecule. The naphthalene ring systems are twisted slightly with respect to the oxadiazole rings, making a dihedral angle of 1.36 (6)°. These molecules are π-stacked along the crystallographic a axis, with an interplanar distance of 3.337 (1) Å. Adjacent molecules are slipped from the `ideal' cofacial π-stack in both the long and short molecular axis (the long molecular axis is defined as the line through the naphthalene C atom in the 6-position and the molecular center, the short molecular axis is in the molecular plane perpendicular to it). The slip distance along the long molecular axis (S1) is 7.064 (1) Å, nearly a two-ring-length displacement. The side slip (S2, along the short molecular axis) is 1.159 (8) Å.
