摘要：
The reaction of Li-2[Phbam(Dipp)] (Phbam(Dipp) = PhB(NDipp)(2); Dipp = 2,6-iPr(2)C(6)H(3)) with lanthanum(III) triiodides LnI(3)(THF)(3.5) (Ln = La, Sm) in THF produces complexes of the type [Li(THF)(4)](2)[(Phbam(Dipp))(2)LnI], which were characterized in solution by multinuclear NMR spectroscopy and in the solid state by single-crystal X-ray structural determinations. The ion-separated complexes are comprised of a spirocyclic anion in which two Phbam(Dipp) ligands and an iodide ion are linked to the five-coordinate metal atom; charge balance is provided by two tetrasolvated lithium ions [Li(THF)(4)](+).
