Reduction of the tris(tert-butylcyclopentadienyl) complexes, Cpt3Ln (Cpt = C5H4CMe3), with potassium in the presence of 18-crown-6 forms the crystallographically characterizable Ln(II) complexes, {[K(18-crown-6)][(μ-Cpt)2CeCpt]}n and [K(18-crown-6)(THF)2][Cpt3Ln] (Ln = Ce, Gd). EPR data indicate that La(II) and Y(II) complexes also form upon reduction of Cpt3Ln. Single crystals of the mixed-valent complexes, [K(18-crown-6)][(μ-Cpt)CeCpt2]2 and [K(2.2.2-cryptand)][Cpt3Dy]2, have also been isolated as part of this study and structurally characterized.
