Abstract:
In the title compound, C(10)H(8)N(3)S(+)·NO(3) (-)·H(2)O, one of the N atoms of the benzimidazole unit is protonated, unlike than that in the thia-zole group. This protonation leads to equalization of the bond angles at the two N atoms of the benzimidazole group. The benzimidazole and thia-zole systems are almost coplanar, forming a dihedral angle of 0.5 (2)°. In the crystal, the nitrate anion and water mol-ecule bridge the thia-bendazolium cations through N-H⋯O and O-H⋯O hydrogen bonds, leading to a supra-molecular network based on an infinite one-dimensional chain using [001] as base vector.

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...
