Abstract

The reaction of mercury(II) chloride with bis(pyridin-3-ylmethyl)sulfane (L, C12H12N2S) in methanol afforded the title crystalline coordination polymercatena-poly[[dichloridomercury(II)]-μ-bis(pyridin-3-ylmethyl)sulfane-κ2N:N′], [HgCl2L]n. The asymmetric unit consists of one HgIIcation, oneLligand and two chloride anions. Each HgIIion is coordinated by two pyridine N atoms from separateLligands and two chloride anions. The metal adopts a highly distorted tetrahedral geometry, with bond angles about the central atom in the range 97.69 (12)–153.86 (7)°. EachLligand bridges two HgIIions, forming an infinite –(Hg–L)n– zigzag chain along thebaxis, with an Hg...Hg separation of 10.3997 (8) Å. In the crystal, adjacent chains are connected by intermolecular C—H...Cl hydrogen bonds, together with Hg—Cl...π interactions [chloride-to-centroid distance = 3.902 (3) Å], that form between a chloride anion and the one of the pyridine rings ofL, generating a two-dimensional layer extending parallel to (101). These layers are further linked by intermolecular C—H...π hydrogen bonds, forming a three-dimensional supramolecular network.
