Silver chalcogenide clusters with dimethylanilinomercapto ligands: Syntheses and crystal structures of [Ag65S13(SC 6H4NMe2)39-(dppm)5], [Ag76Se13(SC6H4NMe2) 50(PPh3)6.5]

Abstract

The core of the matter: Reactions of Ag(PhCO2) with (Me 2N)C6H4(SSiMe3) and E(SiMe 3)2 (E = S, Se) lead to three clusters with new silver chalcogenide cores. For example, the core of [Ag88Se 12(SC6H4NMe2)63(PPh 3)6] (see picture) consists of bent hexagonal layers of selenium and sulfur atoms (yellow), with interstitial silver atoms (blue). The inorganic cores of the clusters are surrounded by organic shells. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
