The title compound, Cu(2)(CN)(SCN)(C(10)H(8)N(2))(2), contains two crystallographically independent Cu(I) atoms, each in a distorted tetra-hedral 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 thio-cyanate 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 thio-cyanate anion is also disordered over two sites, with occupancy factors of 0.61 (3) and 0.39 (3). There are π-π inter-actions between the pyridyl rings of neighbouring chains [centroid-centroid distance = 3.82 (1) Å].
标题化合物[Cu₂(CN)(SCN)(C₁₀H₈N₂)₂]ₙ包含两个晶体学独立的Cu(I)原子，每个原子都处于扭曲的四面体几何构型中。每个Cu原子由一个双齿螯合的2,2'-联吡啶配体配位。一个桥连的氰化物阴离子连接两个Cu(2,2'-联吡啶)单元形成一个双核单元。相邻的双核单元通过硫氰酸根阴离子沿着[010]连接成一维螺旋链。氰化物阴离子无序，每个位点被C和N原子以0.61(5):0.39(5)的占有率占据。硫氰酸根阴离子的S原子也在两个位点上无序，占有率因子分别为0.61(3)和0.39(3)。相邻链的吡啶环之间存在π-π相互作用[质心-质心距离 = 3.82(1) Å]。
