catena-Poly[[(1,10-phenanthroline-κ2N,N′)copper(I)]-μ-thiocyanato-κ2N:S-[(1,10-phenanthroline-κ2N,N′)copper(I)]-μ-cyanido-κ2N:C]

In the title complex, [Cu-2(CN)(NCS)(C12H8N2)(2)], which was synthesized under hydrothermal conditions, both Cu-I atoms have a slightly distorted tetrahedral geometry. They are coordinated by two N atoms of one 1,10-phenanthroline ligand, one bridging thiocyanate anion and one bridging cyanide anion. In the crystal structure, infinite helical {Cu-CN-Cu-SCN}(n) chains are formed along [(1) over bar 01].
