title: 2-Amino-3-carb-oxy-pyrazin-1-ium nitrate monohydrate.
abstract: In crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·NO(3) (-)·H(2)O, inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds link the cations, anions and water mol-ecules into ribbons extending in [10]. Weak inter-molecular C-H⋯O hydrogen bonds further link these ribbons into sheets parallel to (3).
