title: catena-Poly[[di-chlorido-mercury(II)]-μ-1,4-bis-[2-(pyridin-4-yl)ethyn-yl]benzene-κ(2) N:N'].
abstract: In the polymeric title compound, [HgCl2(C20H12N2)] n , the Hg(II) atom is located on a twofold rotation axis and the benzene ring of the bidentate bridging 1,4-bis-[2-(pyridin-4-yl)ethyn-yl]benzene (L) ligand is located about a twofold rotation axis. The Hg(II) atom is coordinated by two N atoms of two different L ligands and by two chloride ions in a distorted tetra-hedral geometry. The dihedral angle between the coordinating pyridine and the benzene ring is 12.8 (2)°. The result of the bridging is the formation of a zigzag chain running parallel to [102]. The chains pack with no specific inter-molecular inter-actions between them.
