(2Z,3Z)-Quinoxaline-2,3(1H,4H)-dione dioxime

چکیده مقاله

The asymmetric unit of the title compound, C8H8N4O2, 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.
