catena-Poly[[trans-dichloro-copper(II)]-mu-1,4,7,10,13,16-hexathia-cyclooctadecane-S-1 : S-10]

In the title complex, [CuCl2(C12H24S6)](n), the CuCl2 unit and the ligand l ie on and about inversion centres, respectively. The coordination geometry at Cu-II is a tetragonally elongated octahedron with the equatorial positio ns occupied by two chlorides, Cu-Cl 2.2786 (12) Angstrom, and two S donors, Cu-S 2.3710 (13) Angstrom. The apical positions of the octahedron are defi ned by two S donors at distances of 2.8261 (14) Angstrom from the metal. Th e macrocyclic ligand adopts a very puckered and distorted conformation. Eig ht of the 18 torsion angles are less than 90 degrees and all S-donors are o riented exo to the ring.
