4-(2-Nitrobenzylideneamino)-3-(1H-1,2,4-triazol-1-ylmethyl)-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C12H10N8O2S, the thione-substituted triazole ring forms dihedral angles of 79.86 (2) and 9.86 (3)°, respectively, with the other triazole ring and the benzene ring. Inter­molecular N—H⋯N hydrogen bonds link the mol­ecules into chains extended along the [101] direction. The crystal packing is further stabilized by van der Waals forces.
