摘要：

Reaction of copper(I) acetate with bis(trimethylsilyl)chalcogenides E-(SiMe(3))(2) (E = S, Se) in the presence of tertiary phosphines in organic solvents leads to the formation of chalcogen-bridged copper clusters in crystalline form. In recent investigations, the following structures were isolated and characterised by X-ray crystallography: [Cu24S12(PMeiPr(2))(12)] (1), [Cu28S14(PtBu(2)Me)(12)] (2), [Cu50S25(PtBu(2)Me)(16)] (3), [Cu70Se35(PtBu(2)Me)(21)] (4), [Cu31Se15(SeSiMe(3))(PtBu(2)Me)(12)] (5) and [Cu48Se24(PMe(2)Ph)(20)] (6). The cluster cores of 1-6 have new structures or new structural characteristics and go some way towards providing an insight into the mechanisms of cluster formation reactions. With the help of the aforementioned compounds a number of structure principles that govern sulfur- and selenium-bridged copper clusters can be formulated.
