Di--chlorido-bis(chlorido{2-[4-(dimethylamino)benzylideneamino]pyridine-N}mercury(II))

Q. Wang and D. Wang

Abstract: The title complex, [Hg₂Cl₄(C₁₄H₁₅N₃)₂], has a centre of symmetry at the centre of the four-membered ring formed by the two Hg and two bridging Cl atoms. Each Hg^II atom is four-coordinated in a distorted tetrahedral coordination geometry by one N atom from the pyridyl ring of a Schiff base ligand, two bridging Cl atoms and one terminal Cl atom. The HgHg distance is 3.774 (2) Å. In the crystal structure, the molecules are linked into a two-dimensional network by intermolecular C-HCl hydrogen bonds.
