Abstract

In the title disulfide, C12H8N6O2S2, all bond lengths and angles are within normal ranges, and the mol-ecules are linked into centrosymmetric R 2 2(20) dimers by simple C - H⋯N inter-actions. Weak inter-molecular C - H⋯π(arene) and π-π inter-actions, involving the benzene CH groups and the benzene rings, and the pyridine rings, respectively, further stabilize and reinforce the crystal structure. © International Union of Crystallography 2007.
