Synthesis and single crystal X-ray structure of a di-copper(I) hexathia macrocyclic complex [Cu2(L)(NCMe)2](ClO4)2(L = 1,4,7,10,13,16-hexathiacyclo-octadecane)

Abstract

1,4,7,10,13,16-hexathiacyclo-octadecane (L)(hexathia-18-crown-6) can bind two copper(I) ions to yield the binuclear complex [Cu₂(L)(NCMe)₂]²⁺; each copper (I) ion is bound in a distorted tetrahedron to three sulphur donor atoms of the hexadentate macrocycle and to one acetonitrile molecule, and the metal–metal separation is 4.25 Å.
