Abstract:
In the mononuclear title complex, [HgCl2(C20H21N3)], synthesized from the quinoline-derived Schiff base N (1),N (1)-diethyl-N (4)-(quinolin-2-yl-methyl-idene)benzene-1,4-di-amine (QMBD), the coordination geometry around the Hg(2+) atom is distorted tetra-hedral, comprising two Cl atoms [Hg-Cl = 2.3654 (19) and 2.4394 (18) Å] and two N-atom donors from the QMBD ligand, viz. one imine and quinoline [Hg-N = 2.334 (5) and 2.340 (5) Å, respectively]. In the crystal, weak C-H⋯Cl hydrogen bonds and weak π-π aromatic ring stacking inter-actions [minimum ring-centroid separation = 3.680 (4) Å] give an overall three-dimensional 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...
