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 [(R^RcSn)₄Sn₂S₁₀] (R^Rc = 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.
