Abstract:
In the title compound, C(7)H(10)N(+)·ClO(4) (-)·C(20)H(24)O(6), the proton-ated benzyl-amine cation forms a rotator-stator complex with the 18-crown-6 (1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne) mol-ecule via N-H⋯O hydrogen bonds. The cations are associated via weak C-H⋯π inter-actions, forming chains parallel to [011], while the perclorate anions are located between these chains.

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...
