Chromatographic Isolation of "Missing" Au55 Clusters ...

We report on the first synthesis of alkanethiolate-protected Au55 (11 kDa), which has been a "missing" counterpart of Schmid's Au55(PR3)12Cl6. Au:SCx clusters (x = 12, 18) were prepared by the reaction of alkanethiol (CxSH) with polymer-stabilized Au clusters (∼1.3 nm) and subsequently incubated in neat CxSH. The resulting clusters were successfully fractionated by …
