4-[(2-Hydroxybenzyl)amino]pyridinium nitrate

The planes of the aromatic rings in the cation of the title salt, C12H13N2O+·NO3−, are twisted along the –CH2—NH– single bond by 75.3 (1)°. In the crystal, the phenol O, amine N and pyridinium N atoms are hydrogen-bond donors to the O atoms of the nitrate counter-ions. These hydrogen bonds lead to the formation of a layer in the crystal.
