Bis(2-amino-3-carb­oxy­pyridinium) sulfate trihydrate

In the title compound, 2C(6)H(7)N(2)O(2) (+)·SO(4) (2−)·3H(2)O, there are two independent cations which are connected into N—H⋯O hydrogen-bonded dimers. In the crystal, O—H⋯O hydrogen-bonded sulfate–water sheets run parallel to (001) and are linked into a three-dimensional network via inter­molecula...

Sumario:In the title compound, 2C(6)H(7)N(2)O(2) (+)·SO(4) (2−)·3H(2)O, there are two independent cations which are connected into N—H⋯O hydrogen-bonded dimers. In the crystal, O—H⋯O hydrogen-bonded sulfate–water sheets run parallel to (001) and are linked into a three-dimensional network via inter­molecular N—H⋯O and O—H⋯O hydrogen bonds through the 2-amino­nicotinium dimers. Further stabilization is provided by weak inter­molecular C—H⋯O hydrogen bonds. R (4) (3)(10) and R (2) (2)(8) graph-set rings are observed. The crystal studied was an inversion twin with refined components of 0.45 (6) and 0.55 (6).
