Abstract

Abstract : Mixed silicon and germanium clusters Si x Ge6− x {N(SiMe3 )Dipp}4 1–3 ( x = 3.7, 3.1, 2.1) with amido-substituents and two ligand-free Ge atoms were obtained in co-reductions using {N(SiMe3 )Dipp}SiBr3 and {N(SiMe3 )Dipp}GeBr3 in three different ratios. Abstract : The synthesis of mixed silicon and germanium clusters Si x Ge6− x {N(SiMe3 )Dipp}4 1–3 ( x = 3.7, 3.1, 2.1) with amido-substituents and two unsubstituted germanium atoms was achieved in co-reductions using the tribromosilane {N(SiMe3 )Dipp}SiBr3 and the tribromogermane {N(SiMe3 )Dipp}GeBr3 in three different ratios. The ratio of Si and Ge used for the synthesis of 1–3 approximately corresponds to that in the final products. All compounds were characterized by single crystal X-ray diffraction and EI mass spectrometry. In addition, 1 and 2 were characterized by solid-state 29 Si{ 1 H} CP/MAS NMR spectroscopy and multinuclear NMR spectroscopy in solution.
