Synthesis, Crystal Structure, and Photoluminescence Studies of a Ruthenocenyl-Decorated Sn/S Cluster

Recently,
we reported on ferrocenyl-decorated Sn/S clusters; herein,
we present the extension of our investigations by attachment of ruthenocenyl
units to an according cluster skeleton. The latter was realized upon
improvement of the synthesis of acetylruthenocene, its conversion
to a hydrazone derivative, and the subsequent reaction with a keto-functionalized
Sn/S precursor complex. The report comprises the crystal structures
of acetylruthenocene and the ruthenocenyl-terminated Sn/S cluster
[(RRcSn)4Sn2S10] (RRc = CMe2CH2­C­(Me)N−NC­(Me)­Rc),
as well as the discussion of the electrochemical properties of the
latter and its behavior during time-resolved photoluminescence investigations.
