Abstract

The interaction of Li[(CH₂)(CH₂)PPh₂] in tetrahydrofuran with one equivalent of [(η⁵-C₅H₄Bu^t)₂ LnCl·LiCl] (Ln = Sm, Yb) gave the anionic lanthanide ate complex [Me₂PPh₂][Ln(η⁵-C₅H ₄Bu^t)₃Cl] (1, Sm) or the neutral lanthanide-ylide complex [(η⁵-C₅H₄Bu^t) 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.
