title: Di-chlorido-(N,N-diethyl-4-{[(quinolin-2-yl)methyl-idene]amino-κ(2) N,N'}aniline)mercury(II).
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.
