Crystal structure of the coordination polymer catena-poly[[[(acetonitrile-κN)copper(I)]-μ(3)-1,3-dithiolane-κ(3) S:S:S′] hexafluoridophosphate]

The polymeric title compound, [Cu(2)(C(2)H(3)N)(2)(C(3)H(6)S(2))(2)](PF(6))(2), represents an example of a one-dimensional coordination polymer resulting from the reaction of [Cu(MeCN)(4)][PF(6)] with 1,3-di­thiol­ane. The cationic one-dimensional ribbon consists of two copper(I) centers each ligated by one aceto­nitrile mol­ecule and inter­connected through two bridging 1,3-di­thiol­ane ligands. One S-donor site of each ligand is κ(1)-bound to Cu, whereas the second S atom acts as a four-electron donor, bridging two Cu atoms in a κ(4)-bonding mode. The positive charge of each copper cation is compensated for by a hexa­fluorido­phosphate counter-ion. In the crystal, the polymer chains are linked by a series of C—H⋯F hydrogen bonds, forming a supra­molecular framework.
