title: (2Z,3Z)-Quinoxaline-2,3(1H,4H)-dione dioxime.
abstract: 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.
