Abstract:
Ihe title salt, C(8)H(6)F(3)N(2) (+)·NO(3) (-), the F atoms of the triflouromethyl group are disordered over two sets of sites in a 0.58 (2):0.42 (2) ratio. In the crystal, N-H⋯O hydrogen bonds link the cations and anions into chains running parallel to the b axis. There is π-π stacking between symmetry-related benzene rings with a centroid-centroid distance of 3.949 (3) Å. The crystal studied was a non-merohedral twin, with a 19% minor component.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
