Dichlorido(4-{[(quinolin-2-yl)methylidene]amino}phenol-κ2N,N′)mercury(II)

Abstract

In the mononuclear title complex, [HgCl2(C16H12N2O)], synthesized from the phenolic Schiff base 4-[(quinolin-2-ylmethylidene)amino]phenol (QMAP), the coordination geometry around Hg2+is distorted tetrahedral, comprising two Cl atoms [Hg—Cl = 2.3565 (12) and 2.5219 (12) Å] and two N-atom donors from the QMAP ligand,viz.one imine and the other quinoline [Hg—N = 2.392 (2) and 2.237 (2) Å, respectively]. In the crystal, O—H...Cl hydrogen bonds generate a chain structure extending along thec-axis direction. Weak C—H...Cl and π–π stacking interactions [minimum ring centroid separation = 3.641 (3) Å] give an overall layered structure lying parallel to (001).
