Abstract:
In the mononuclear title complex, [HgCl2(C16H12N2O)], synthesized from the phenolic Schiff base 4-[(quinolin-2-yl-methyl-idene)amino]-phenol (QMAP), the coordination geometry around Hg(2+) is distorted tetra-hedral, 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 the c-axis direction. Weak C-H⋯Cl and π-π stacking inter-actions [minimum ring centroid separation = 3.641 (3) Å] give an overall layered structure lying parallel to (001).
