摘要：
Tripodal tris(siloxide) ligand supported rare-earth metal complexes LLn(iii) (Ln = Ce, Pr, Tb, Y, Lu) were synthesized. The Ce(iii) complex was oxidized with [N(C6H4Br)3][SbCl6] to a Ce(iv) chloride complex, which reacted with tBuONa to form a Ce(iv) tert-butoxide complex, one displaying a reduction potential cathodically shifted relative to that of Ce(iv) chloride complex. Tetravalent cerium chloride and tert-butoxide complexes supported by a tripodal tris(siloxide) ligand showed substantial stability.
