Syntheses and Crystal Structures of the New Ag-S Clusters [Ag70S16(SPh)34(PhCO2)4(triphos)4] and [Ag188S94(PR3)30]

Syntheses and Crystal Structures of the New Ag-S Clusters [Ag70S16(SPh)34(PhCO2)4(triphos)4] and [Ag188S94(PR3)30]

An almost spherical cluster with a diameter of about 2.5 nm is formed by Ag atoms (blue), S2− ligands (yellow), and P atoms (green) of PnPr3 ligands in [Ag188S94(PnPr3)30] (see picture). The phosphane ligands from the spherical Ag2S cluster core point out like the spines of a hedgehog. The sulfur su...

Zusammenfassung:An almost spherical cluster with a diameter of about 2.5 nm is formed by Ag atoms (blue), S2− ligands (yellow), and P atoms (green) of PnPr3 ligands in [Ag188S94(PnPr3)30] (see picture). The phosphane ligands from the spherical Ag2S cluster core point out like the spines of a hedgehog. The sulfur substructure is constructed from three almost spherical shells.
