A functionalized Ag2S molecular architecture: facile assembly of the atomically precise ferrocene-decorated nanocluster [Ag74S19(dppp)6(fc(C{O}OCH2CH2S)2)18].

ABSTRACT

A ferrocene-based dithiol 1,1'-[fc(C{O}OCH2CH2SH)2] has been prepared and treated with a Ag(I) salt to form the stable dithiolate compound [fc(C{O}OCH2CH2SAg)2]n (fc=[Fe(η(5)-C5H4)2]). This is used as a reagent for the preparation of the nanocluster [Ag74S19(dppp)6(fc(C{O}OCH2CH2S)2)18] which was obtained in good yield (dppp=1,3-bis(diphenylphosphino)propane).
