| Abstract: | Synthesis and Structure of Tetrameric Tris(trimethylsilyl)indium(I) and of New Silyl substituted Indium Compounds The reaction of InCp* with LiSi(SiMe3)3·3thf] yielded in the first silylsubstituted tetrahedrane of indium In4{Si(SiMe3)3}4] ( 1 ). It crystallizes together with In{Si(SiMe3)3}3] ( 2 ) in dark green crystals. Colourless crystals of Li(OH)(OSiMe3)In{Si(SiMe3)3}2]2 ( 3 ) were isolated as a byproduct from this reaction. It's structural core are three connected four membered rings made up of In‐, Li‐ and O‐atoms. From the reaction of InOSO2CF3] with LiSi(SiMe3)3·3thf] colourless crystals of In{Si(SiMe3)3}2OSO2CF3·thf] ( 4 ) were isolated. InCp* reacted with LiSiMe(SiMe3)2·3thf] to form the orange‐coloured monoindane In{SiMe(SiMe3)2}3] ( 5 ). 1 – 4 were characterized by X‐ray crystal structure analyses. |
