Abstract

The synthesis and structures of the first zwitterionic divalent rare-earth metal silanides of the formula [Si(SiMe₂OMe)₃-κ³]₂M (M-3), where M = Eu, Yb, and Sm, are reported. M-3 compounds feature spirocyclic bicyclooctane structures in which the central rare-earth metal ions are being octahedrally coordinated by six methoxy groups. The reaction of Yb-3 with BPh₃ and W(CO)₆ respectively generated the trinuclear zwitterions [Ph₃BSi(SiMe₂OMe)₃-κ³]₂Yb (Yb-4) and [(CO)₅WSi(SiMe₂OMe)₃-κ³]₂Yb (Yb-5) in good yield.
