2-Amino-5-methyl­pyridinium 1H-pyrazole-3,5-dicarboxyl­ate trihydrate

In the title compound, 2C(6)H(9)N(2) (+)·C(5)H(2)N(2)O(4) (2−)·3H(2)O, the 1H-pyrazole-3,5-dicarboxyl­ate anion is close to planar [maximum deviation = 0.208 (1) Å]. The two distinct 2-amino-5-methyl­pyridinium cations are also almost planar, with maximum deviations of 0.018 (2) and 0.014 (2) Å. In the crystal, pairs of inter­molecular N—H⋯O and O—H⋯O hydrogen bonds connect neighbouring mol­ecules into dimers, generating R (2) (2)(8) and R (2) (4)(8) ring motifs, respectively. Further inter­molecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network.
