Shahani T, Fun HK, Hemamalini M - Acta Crystallogr Sect E Struct Rep Online (2010)

Bottom Line: The two distinct 2-amino-5-methyl-pyridinium cations are also almost planar, with maximum deviations of 0.018 (2) and 0.014 (2) Å.In the crystal, pairs of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect neighbouring mol-ecules into dimers, generating R(2) (2)(8) and R(2) (4)(8) ring motifs, respectively.Further inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

ABSTRACT
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-dicarboxyl-ate anion is close to planar [maximum deviation = 0.208 (1) Å]. The two distinct 2-amino-5-methyl-pyridinium cations are also almost planar, with maximum deviations of 0.018 (2) and 0.014 (2) Å. In the crystal, pairs of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect neighbouring mol-ecules into dimers, generating R(2) (2)(8) and R(2) (4)(8) ring motifs, respectively. Further inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
