Abstract
The title compounds can be synthesized by fusion reaction of the alkali carbonates with copper and sulfur at 790 °C. The structure was solved from X-ray diffractometer data of single crystals and refined to an R-value of 0.06. The compounds crystallize with the same layer-type structure which is closely related to that of KCU3S2. Crystal data for K3Cu8S6 (Rb3Cu8S6): space group C2/m,z = 2, ϱcalc = 4.27(4.76) g/cm 3 , a = 17.332(4) (17.840(6)) Å, b = 3.830(2) (3.865(1)) Å, c = 9.889(4) (10.011(3)) Å, β = 104.12(2)° (104.91(2)°).Keywords
