| Abstract: | The Tris(cyclopentadienyl)methylsilane Trianion – a New Ligand System and Complex Formation with Rhodium Starting from MeSiCl3 the title compound was synthesized by two steps as the virtually insoluble trithallium salt ( 1 ). Reaction of 1 with [(C2H4)2RhCl]2 in pentane gives {MeSi[C5H4Rh(C2H4)2]3} ( 2 ). Under UV irradiation of 2 in pentane in the presence of benzene only two [C5H4Rh(C2H4)2] units of 2 react with loss of ethene and formation of the μ-η3 : η3 benzene compound {MeSi[(C5H4Rh)2(C6H6)][C5H4Rh(C2H4)2]} ( 3 ). The novel complexes 2 and 3 were characterized spectroscopically and by X-ray structure analysis. |
