On Chalcogenolates. 197. Studies on Polythiocuprates(I) Cu(S_x)]^?. 1. Properties and Reactions of Ammonium Tetrathiocuprate(I) The properties of NH₄Cu(S₄)] have been studied. In watery alkaline media it decomposes into CuS and S; in the presence of carbon disulfide CuS, S_x^2?, and CS₃^2? besides CS₄^2? and S₂CO^2? are formed. The compound (NH₄)₂Cu₂CS₇], described in literature, does not exist. In dimethylformamide dissolved NH₄Cu(S₄)] decomposes via the radical anion S₃^?. NH₄Cu(S₄)] reacts with n-butyl chloride to yield the substituted sulfanes (C₄H₉)₂S_x with x = 1, 2, and 3.
