Abstract:
In the title coordination polymer, [HgCl(2)(C(11)H(9)N(3))](n), the Hg(II) ion is coordinated by three N atoms from two N-[(E)-pyridin-2-yl-methyl-idene]pyridin-3-amine (L) ligands and two chloride anions in a distorted trigonal-bipyramidal geometry. The two pyridine rings in L form a dihedral angle of 50.0 (2)°. L ligands bridge adjacent HgCl(2) units into polymeric chains propagating in [010]. The crystal packing is further stabilized by weak inter-molecular C-H⋯Cl hydrogen bonds and π-π inter-actions between the pyridine rings, with a centroid-centroid separation of 3.529 (9) Å.

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...
