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-di-thiol-ane. The cationic one-dimensional ribbon consists of two copper(I) centers each ligated by one aceto-nitrile mol-ecule and inter-connected through two bridging 1,3-di-thiol-ane 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 hexa-fluorido-phosphate counter-ion. In the crystal, the polymer chains are linked by a series of C-H⋯F hydrogen bonds, forming a supra-molecular framework.
