2-Cyanoquinolin-1-ium nitrate

W.-S. Loh, M. Hemamalini and H.-K. Fun

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 R₂¹(4) ring motif. C-HO hydrogen bonds link the ions into sheets stacking along the a axis.
