4-[(3-Nitro­benzyl­idene)amino]-3-(pyridin-4-yl)-1H-1,2,4-triazole-5(4H)-thione

In the title compound, C₁₄H₁₀N₆O₂S, the dihedral angle between the pyridine and triazole rings is 3.21 (10)°. The mol­ecule is significantly twisted about the N_t—N_b (t = triazole and b = benzyl­idene) bond [C—N_t—N_b=C = 151.64 (17)°]. In the crystal, mol­ecules are linked by weak N—H...N hydrogen bonds, generating C(8) chains propagating in [10].
