Descripción
Sumario:The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), 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 R (2) (2)(10) motifs, leading to layers, which inter­act via phen­yl–phenyl inter­actions (C⋯C distances in the range 3.238–3.521 Å).
