| Description |
A stable, Ag-55 cluster protected with 4-(tert-butyl) benzyl mercaptan (BBSH) was synthesized which exhibits two prominent absorption bands with maxima at 2.25 and 2.81 eV. A molecular ion peak at m/z 11500 +/- 20 in matrix assisted laser desorption ionization mass spectrum (MALDI MS), assigned to Ag-55(BBS)(31) was observed. Electrospray ionization (ESI MS) shows a prominent trication along with higher charged species. An analogous Ag-55(PET) (31) (PET = 2-phenylethanethiol, in the thiolate form) was also synthesized under optimized conditions which proves the amenability of this cluster and the synthetic methodology to other ligands.
