The asymmetric unit of the title compound, C(2)H(2)N(4)O(2), contains two crystallographically independent mol-ecules in which the triazole rings are essentially planar, with maximum deviations of 0.003 (1) Å in both molecules. The dihedral angle between the two 1H-1,2,4-triazole rings is 56.58 (5)°. In the crystal, mol-ecules are linked via inter-molecular N-H⋯N and C-H⋯O hydrogen bonds, forming a supra-molecular chain along the b axis.
