Figure 1 The mol­ecular structure of C13H9N3O6, showing the atom numbering scheme and 50% probability displacement ellipsoids. H1O (0.36 (3) occupancy) has been omitted from O1 in the diagram and only the predominant component, H2O (0.64 (3) occupancy), has been shown. Dashed lines indicate intra­molecular N–H⋯O hydrogen bonds.
