Abstract
AbstractThe reaction of copper(I) acetate with mixtures of PhSSiMe3 and Se(SiMe3)2 in the presence of PPh3 leads to a series of new cluster compounds consisting of a copper selenide core surrounded by a sulfide shell: [Cu17Se(SPh)15(PPh3)4], [Cu20Se(SPh)12(OAc)6(PPh3)4], [Cu28Se6(SPh)16(PPh3)8], [Cu36Se8(SPh)20(PPh3)8], [Cu54Se8(SPh)30(OAc)8(PPh3)6], and[Cu72Se14(SPh)36(OAc)8(PPh3)6]. They have been structurally characterized by single‐crystal X‐ray analysis. The two smallest clusters have a ball‐like structure with one selenium atom in the center totally enclosed by sulfur atoms. In the other clusters the inner copper–selenium core is surrounded by an incomplete sulfur shell varying between 53 and 87 % coverage. (© Wiley‐VCH Verlag GmbH & Co.
