title: 8-Hy-droxy-quinolin-1-ium nitrate.
abstract: In the title salt, C(9)H(8)NO(+)·NO(3) (-), the quinoline ring system is essentially planar with a maximum deviation of 0.043 (1) Å. In the crystal, an R(2) (2)(7) ring motif is formed by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds between the cation and the anion. In addition, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link the two ions, generating an R(2) (2)(8) ring motif. These sets of ring motifs are further linked into a ribbon along the a axis via inter-molecular C-H⋯O hydrogen bonds.
