Abstract
The\ninfluence of the stabilizing ligand on the physical and chemical\nproperties of a metalloid cluster compound is important for nanotechnology\nas metalloid clusters are ideal model compounds for metal nanoparticles.\nHere we present the synthesis of a differently substituted metalloid\n{Ge<sub>9</sub>R<sub>3</sub>}<sup>−</sup> cluster: {Ge<sub>9</sub>[Si(SiMe<sub>3</sub>)<sub>2</sub>(SiPh<sub>3</sub>)]<sub>3</sub>}<sup>−</sup> <b>1</b>, which is obtained in\ngood yield by the reaction of K<sub>4</sub>Ge<sub>9</sub> with ClSi(SiMe<sub>3</sub>)<sub>2</sub>(SiPh<sub>3</sub>). <b>1</b> is characterized\nvia NMR and mass spectrometry, but crystallization is hindered. However,\nthe reaction with HgCl<sub>2</sub> gives the neutral compound HgGe<sub>18</sub>[Si(SiMe<sub>3</sub>)<sub>2</sub>(SiPh<sub>3</sub>)]<sub>6</sub> <b>2</b>, which can be crystallized and structurally\ncharacterized. The presented results are a first step for the investigation\nof the ligand’s influence on the properties of a metalloid\ngermanium cluster compound.
