The asymmetric unit of the title salt, C6H16NO+·C10H4ClN4O7 −·0.5H2O, contains two cations, two anions and one water mol­ecule. In one independent anion, one nitro group is rotationally disordered over two orientations in a 0.657 (8):0.343 (8) ratio. In the crystal, inter­molecular N—H⋯O and O—H⋯O hydrogen bonds link all the components into ribbons extending along [100].

In the cation of the title hydrated salt, C11H9N4O4 +·Cl−·H2O, the six-membered rings are inclined to each other at 79.0 (1)° and an intra­molecular N—H⋯O hydrogen bond occurs. In the crystal, N—H⋯Cl hydrogen bonds link two cations and two anions into centrosymmetric group, and O—H⋯Cl hydrogen bonds involving the water mol­ecules further link these groups into chains in [101]. An O—H⋯O inter­action is also present. The water mol­ecule is disordered over two sets of sites in a 0.555 (13):0.445 (13) ratio
