2,5-Bis(5-methylpyrazin-2-yl)-1,3,4-oxadiazole

In the title molecule, C12H10N6O, the dihedral angle between the two pyrazine rings [planar to within 0.009 (3) and 0.018 (3) Å] is 5.62 (15)°. They deviate from the central oxadiazole ring [planar to within 0.005 (3) Å] by 1.52 (16) and 5.55 (17)°, respectively. In the crystal, C—H...N interactions involving the pyrazine rings connect molecules to form zigzag supramolecular chains propagating in [010].
