The title compound, [AgCd(NCS)(3)(C(22)H(17)N(3))](n), is a hetero-atom ribbon coordination polymer. The central Cd atom is chelated by the 4'-p-tolyl-2,2':6',2''-terpyridine ligand and is coordinated by the N atoms of three thio-cyanate ions in an octa-hedral geometry whereas the Ag atom is coordinated by the four S atoms of four thio-cyanate ions in a distorted tetra-hedral geometry. Of the three thio-cyanate ions, one functions in a μ(2)-bridging mode and two in a μ(3)-bridging mode. The ribbon coordination polymer propagates along the a-axis.
