| Abstract: The product of reaction between hexahydropyridium cyclohexyldithioformate and CuCl2 was rccrystallizcd from CS2 to give Cu4(c-C6H11CSS2)4. Its structure was determined by a singlecrystal diffraction analysis. The crystal belongs to space group C4h4-P42/n with a= b=15.125Å, c=8.514Å, α = β = γ = 90° P=1948Å3, Z = 2. R = 0.040 for 929 reflections. In the molecule the Cu4 core has a distored tetrahedron configuration. A redox reaction is involved in the reaction between c-C6H11CS2- and Cu2+. Some mechanisms in the formation of Cu4(c-C6H11CSS2)4 are discussed. |
