Abstract: The title compound, [Cu₂(CN)(SCN)(C₁₀H₈N₂)₂]_n, contains two crystallographically independent Cu^I atoms, each in a distorted tetrahedral geometry. Each Cu atom is coordinated by a bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units to form a binuclear unit. Adjacent binuclear units are connected by a thiocyanate anion into a one-dimensional helical chain along [010]. The cyanide anion is disordered, with each site occupied by both C and N atoms in an occupancy ratio of 0.61 (5):0.39 (5). The S atom of the thiocyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are - interactions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].
