The asymmetric unit of the title compound, C(8)H(8)N(4)O(2), contains one half-mol-ecule; a twofold rotation axis bisects the molecule. An intra-molecular N-H⋯O hydrogen bond results in the formation of a five-membered ring, which displays an envelope conformation. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link the mol-ecules.
