Crystal and molecular structure of the polymeric complex chloro(2,5-dithiahexane)copper(I)

Abstract

The crystal and molecular structure of the title complex has been determined by single-crystal X-ray diffraction techniques, from diffractometer data. The crystals are monoclinic, with a= 7.673(2), b= 6.727(2), c= 15.700(5)A, β= 104.8 °, Z= 4, and space group P21/c. The tructure has been refined by full-matrix least-squares methods to a final R factor of 0.035 for 1710 independent reflections. The complex is polymeric, with adjacent molecules in the crystal joined by a bond between the copper atom of one molecule and one of the sulphur atoms of the dithiahexane ligand of a neighbouring molecule. Each copper atom has a distorted-tetrahedral geometry, with two bonds to the sulphur atoms of the dithiahexane ligand [Cu–S 2.336(1) and 2.342(1)A], one to a terminal chlorine atom [Cu–Cl 2.239(1)A], and one to one sulphur atom of a neighbouring molecule [Cu–S 2.315(1)A].
