Abstract: In the title coordination polymer, [CuI(C₁₄H₁₈N₄S₂)]_n, the Cu^I center is trigonally coordinated by two pyrimidine N-atom donors from two distinct dithioether ligands and one iodide anion. The Cu and I atoms are located on a twofold axis, whereas the midpoint of the central C-C bond of the dithioether ligand is located on an inversion center. Each organic ligand, acting in a bidentate mode, bridges two Cu^I ions, resulting in the formation of polymeric zigzag chains. The dihedral angle between the two pyrimidine units bonded to the metal center is 88.01 (2)°. The crystal packing is mainly stabilized by van der Waals forces and - stacking interactions, with an interplanar distance between the pyrimidine rings of adjacent chains of 3.638 (3) Å.
