摘要：

The preparation of [(Me(3)C)(2)C5H3]Ce-3 from Ce(OSO2CF3)(3) and [(Me(3)C)(2)C5H3]Mg-2 is described and compared to published routes to other Cp(3)Ln(Ln = lanthanide) compounds. The title compound is monomeric in the solid state with three eta(5)-bound cyclopentadienyl rings which show some unusual distortions while maintaining idealized C-3h symmetry. The crystals are monoclinic, in the space group P2(1)/n, with the unit cell a 10.803(3) b 19.493(6) c 17.946(5) Angstrom, beta 104.35(2)degrees, Z = 4. Anisotropic refinement of all heavy atoms with 361 parameters and 3420 reflections yielded R = 4.62%.
