In the cation of the title hydrated salt, C(11)H(9)N(4)O(4) (+)·Cl(-)·H(2)O, the six-membered rings are inclined to each other at 79.0 (1)° and an intra-molecular 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 mol-ecules further link these groups into chains in [101]. An O-H⋯O inter-action is also present. The water mol-ecule is disordered over two sets of sites in a 0.555 (13):0.445 (13) ratio.
