2-Cyanoquinolin-1-ium nitrate

Abstract

A proton is transferred from the nitric acid to the N atom of 2-cyano­quinoline during crystallization, resulting in the formation of the title salt, C10H7N2 +·NO3 −. The quinolinium ring system is approximately planar, with a maximum deviation of 0.013 (3) Å. In the crystal, a very asymmetric bifurcated N—H⋯(O,O) hydrogen bond to two O atoms of an adjacent nitrate anion occurs, generating an R 2 1(4) ring motif. C—H⋯O hydrogen bonds link the ions into sheets stacking along the a axis.
