Abstract: Reaction of 4'-phenyl-2,2':6',2''-terpyridine (phtpy), copper acetate hydrate and ammonium thiocyanate under solvothermal conditions led to the formation of the title compound, {[Cu(C₂₁H₁₅N₃)₂][Cu₂(NCS)₄]}_n. The structure is composed of discrete [Cu(phtpy)₂]²⁺ cations and polymeric anionic {[Cu(SCN)₂]^-} chains propagating along [010]. The central Cu²⁺ ion in the cation is coordinated by two tridentate chelating phtpy ligands in a distorted octahedral geometry. In each of the two crystallographically independent centrosymmetric anions, the Cu^I atoms are bridged in a 1,3-₂-bridging mode by two S and two N atoms, resulting in a distorted tetrahedral CuN₂S₂ coordination. The [Cu(phtpy)₂]²⁺ cations are fixed between these polymers by intermolecular C-HS hydrogen bonds.
