Abstract
A novel high-nuclearity silver(I) ethynide cluster complex, namely {SiF6@Ag-24(C (CBu)-Bu-t)(20)}center dot SiF6, has been isolated from the reaction between AgBF4 and (BuC)-Bu-t CAg in a glass beaker. Single-crystal X-ray analysis showed that an in situ generated hexafluorosilicate template anion occupies the central cavity of the cationic polyhedral Ag-24 cluster, which is consolidated by peripheral tert-butyl ethynide groups and inter-cluster hexafluorosilicate ions.
