Donors and other Components

Copper(i) monothiocarbonates, Cu (SOCOR), (R = Me, Et, or Bun), are formed by reaction of the potassium monothiocarbonates with copper(n) salts.660 

The structure of cyclo-di-p- bis-[2-(NiV-dimethylamino)ethyl]disulphide dicop-per(i) tetrafluoroborate, Cu2(Me2NCH2CH2SSCH2CH2NMe2)(BF4)2, contains a central CuSSCuSS ring (152), the Cu1 being in a very badly distorted tetrahedral environment. The complex is prepared by reaction of the ligand with either Cu1 or Cu11 ions in the latter case, the ligand reduces the metal to the required oxidation state.661
