    Description / Table of Contents: On Chalcogenolates. 197. Studies on Polythiocuprates(I) [Cu(Sx)]-. 1. Properties and Reactions of Ammonium Tetrathiocuprate(I)The properties of NH4[Cu(S4)] have been studied. In watery alkaline media it decomposes into CuS and S; in the presence of carbon disulfide CuS, Sx2-, and CS32- besides CS42- and S2CO2- are formed. The compound (NH4)2[Cu2CS7], described in literature, does not exist.In dimethylformamide dissolved NH4[Cu(S4)] decomposes via the radical anion S3-.NH4[Cu(S4)] reacts with n-butyl chloride to yield the substituted sulfanes (C4H9)2Sx with x = 1, 2, and 3.
    Notes: Die Eigenschaften von NH4[Cu(S4)] wurden untersucht. In wäßrig-alkalischem Medium zersetzt es sich in CuS und S; in Gegenwart von Kohlenstoffdisulfid werden vorwiegend CuS, Sx2- und CS32- neben CS42- und S2CO2- gebildet. Die in der Literatur beschriebene Verbindung (NH4)2[Cu2CS7] konnte nicht isoliert werden.In Dimethylformamid gelöstes NH4[Cu(S4)] zersetzt sich unter primärer Bildung des Radikalanions S3-, das dann weiter zerfällt.NH4[Cu(S4)] reagiert mit n-Butylchlorid zu den substituierten Sulfanen (C4H9)2Sx mit x = 1, 2 und 3.
