Abstract

The synthesis and X-ray determination of two sulfur bridged copper clusters with the known compositions of [Cu12S6(PnPr3)8] and [Cu20S10(PnBu1Bu2)8] but new molecular structures allow a comparison of these isomeric copper sulfide clusters. The Cu-S frameworks of the clusters with twelve copper atoms are highly topologically related and can both be derived flom a hypothetical “naked” [Cu12,S6] cluster that results from theoretical investigations. More dificult is the comparison of the two clusters containing 20 metal atoms. The two cluster types can be called either a “prolate” or an “oblate” isomer of [Cu20S10(pR3)8].
