Abstract:
In the title complex, [Zn(C(10)H(8)N(5))Cl](n), the Zn(II) ion is four-coordinated by one Cl atom and three N atoms from two in situ-generated deprotonated 5-(1-methyl-1H-benzimidazol-2-yl-κN(3))-1,2,3-triazol-1-ide ligands in a slightly distorted tetra-hedral geometry. The Zn(II) ions are bridged by the ligands, forming a helical chain along [001]. C-H⋯N and C-H⋯Cl hydrogen bonds and π-π inter-actions between the imidazole rings [centroid-centroid distance = 3.4244 (10) Å] assemble the chains into a three-dimensional supra-molecular network.

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...
