o-Benzoquinone dioxime

Abstract

The title compound, C6H6N2O2, was obtained as a product of an in vitro study of the metabolism of benzofuroxan. The molecule exhibits a amphi configuration of the oxime groups C=N—OH. One oxime group is involved in the formation of a strong intramolecular O—H...N hydrogen bond, while another links molecules into zigzag chains along the c axis via intermolecular O—H...N hydrogen bonds.
