“…The molecular structure of decasilaadamantane 24 in the solid-state is depicted in Figure 3. 108 Two more examples of polycyclic decasilanes were reported in 2017 by Kyushin and co-workers with the persilahexahydrotriquinacene 26 featuring a [5.2.1.0 4,10 ]tricyclic scaffold and persilaisotwistane 27 with a [4.3.1.0 3,7 ]tricyclic scaffold. Both are accessible by reduction of the hexabrominated, branched decasilane 25 in 5% and 3% yield, respectively (Scheme 14).…”

The continuously decreasing size of device features in microelectronics draws growing attention to the structuring of silicon at the molecular level with powerful tools provided by synthetic chemistry. Silicon clusters are of particular importance in this regard not only as potential precursors for silicon deposition but also as well-defined model systems for bulk and surfaces of silicon at the nanoscale as well as possible starting points for future construction of molecularly precise device structures. This review aims to give a comprehensive overview about the state of the art in the synthesis of molecular silicon clusters, which are grouped into (1) electron-precise saturated clusters, (2) soluble polyhedral Zintl anions, and (3) unsaturated silicon clusters, the so-called siliconoids. Particular attention is paid to functionalization as it is generally considered a necessary prerequisite for the design and construction of more extended systems. The interrelations between the three different classes of molecular silicon clusters, e.g., arising from the introduction of negatively charged functional groups, are highlighted on grounds of NMR properties and computed electronic structures.
