1,4-Dihydroxyquinoxaline-2,3(1H,4H)-dione

The asymmetric unit of the title compound, C8H6N2O4, contains one half-molecule; a twofold rotation axis bisects the molecule. The quinoxaline ring is planar, which can be attributed to electron delocalization. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecu...

description The asymmetric unit of the title compound, C8H6N2O4, contains one half-molecule; a twofold rotation axis bisects the molecule. The quinoxaline ring is planar, which can be attributed to electron delocalization. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules into R22(10) motifs, leading to layers, which interact via phenyl–phenyl interactions (C...C distances in the range 3.238–3.521 Å).
