title: catena-Poly[[iodidocopper(I)]-μ-4,4',6,6'-tetra-methyl-2,2'-(ethyl-enedithio)dipyrimidine-κN:N'].
abstract: In the title coordination polymer, [CuI(C(14)H(18)N(4)S(2))](n), the Cu(I) center is trigonally coordinated by two pyrimidine N-atom donors from two distinct dithio-ether 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 dithio-ether 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 π-π stacking inter-actions, with an inter-planar distance between the pyrimidine rings of adjacent chains of 3.638 (3) Å.
