In the titledisulfide, C12H8N6O2S2, all bond lengths and angles are within normal ranges, and the molecules are linked into centrosymmetric R-2(2)( 20) dimers by simple C - H center dot center dot center dot N interactions. Weak intermolecular C - H center dot center dot center dot pi( arene) and pi-pi interactions, involving the benzene CH groups and the benzene rings, and the pyridine rings, respectively, further stabilize and reinforce the crystal structure.
