title: 3,5-Dicarboxyanilinium nitrate dihydrate.
abstract: In the crystal of the title compound, C(8)H(8)NO(4) (+)·NO(3) (-)·2H(2)O, the 5-ammonio-isophthalic acid cations, the nitrate anions and the water mol-ecules are linked by N-H⋯O, O-H⋯O and C-H ⋯O hydrogen bonds into a three-dimensional network. The structure is further stabilized by aromatic π-π stacking inter-actions, with centroid-centroid separations of 3.827 (2) Å.
