摘要：

Reduction of the tris(tert-butylcyclopentadienyl) complexes, Cp(3)(t)Ln (Cp-t = C5H4CMe3), with potassium in the presence of 18-crown-6 forms the crystallographically characterizable Ln(II) complexes, {[K(18-crown-6)][(mu-Cp-t)(2)CeCpt]}(n) and [K(18-crown-6)(THF)2][Cp(3)(t)Ln] (Ln = Ce, Gd). EPR data indicate that La(II) and Y(II) complexes also form upon reduction of Cp(3)(t)Ln. Single crystals of the mixed-valent complexes, [K(18-crown-6)][(mu-Cp-t)CeCpt(2)]2 and [K(2.2.2-cryptand)][(Cp3Dy)-Dy-t](2), have also been isolated as part of this study and structurally characterized.
