In the title compound, [Cu(C(2)N(3))(C(10)H(8)N(2)S(2))](n), the Cu(I) atoms are connected by bridging dicyanamide ligands, forming chains parallel to [100]. Each Cu(I) atom displays a tetra-hedral coordination environment, formed by one S atom and three N atoms from one 2-(pyridin-2-yldisulfan-yl)pyridine and two dicyanamide ligands. The crystal structure is stabilized by C-H⋯N hydrogen bonds, forming a three-dimensional network.
