Abstract
The structure of the title compound, {(C(5)H(5)ClN)(2)[Hg(3)Cl(8)]}(n), consists of 4-chloropyridinium cations and one-dimensional [Hg(3)Cl(8)](2-) anion chains. There are two coordination environments for Hg(II) in the inorganic chain. The first is a distorted tetrahedral geometry made up of an HgCl(2) unit with two Cl(-) anion bridges, while the second is an octahedral coordination geometry consisting of an HgCl(2) unit and four chloride-anion bridges. This gives rise to a novel three-layer centrosymmetric polymer. Finally, the three-dimensional network comes about through the many C-H···Cl and N-H···Cl hydrogen bonds that link the organic and inorganic layers.
