A Functionalized Ag2S Molecular Architecture: Facile Assembly of the Atomically Precise Ferrocene-Decorated Nanocluster [Ag74S19(dppp)6(fc(C{O}OCH2CH2S)2)18]

A ferrocene‐based dithiol 1,1′‐[fc(C{O}OCH2CH2SH)2] has been prepared and treated with a AgI salt to form the stable dithiolate compound [fc(C{O}OCH2CH2SAg)2]n (fc=[Fe(η5‐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). All wrapped up! A ferrocenyl‐based dithiol reagent has been employed as a precursor for the preparation of a surface‐functionalized Ag74S55 nanocluster [Ag74S19(dppp)6(fc(C{O}OCH2CH2S)2)18] (dppp=1,3‐bis(diphenylphosphino)propane, fc=[Fe(η5‐C5H4)2]). The electrochemical properties and single‐crystal X‐ray structure of the cluster are reported (atom colors: Ag=blue, S=yellow, P=green, O=red, Fe=orange, C=gray).
