The interaction of Li[(CH2)(CH2)PPh2] in tetrahydrofuran with one equivalent of [(η5-C5H4But)2 LnCl·LiCl] (Ln = Sm, Yb) gave the anionic lanthanide ate complex [Me2PPh2][Ln(η5-C5H 4But)3Cl] (1, Sm) or the neutral lanthanide-ylide complex [(η5-C5H4But) 2Ln(Cl)CH2P(Me)Ph2] (3, Yb). The interaction of LnCl3 (Ln = Er, Yb) in tetrahydrofuran with two equivalents of NaNPh2 followed by one equivalent of Li[(CH2) (CH2)PPh2] gave the unexpected anionic homoleptic tetra-coordinate lanthanide-amide ate complex, [Li (C4H8O)4][Ln(NPh2)4] (4, Er; 5, Yb). All of these complexes have been characterized by analytical and spectroscopic methods. The structures of 1 and 4 have been established by X-ray diffraction.
