Naphthaleneytterbium, C10H8Yb(THF)3, reacts with Cp2Cr, Cp2Co, Cp2Ni, and Cp2V in THF to give Cp2Yb.In the case of the reaction of C10H8Yb(THF)3 with Cp2V, vanadium-containing intermediates could be isolated.One of them, CpVC10H8VCp, has been characterized by X-ray diffraction.The crystals are monoclinic, space group P2₁/n, with a 907.0(5), b 798.8(3), c 1080.8(5) pm, β 105.21(4) deg; Z = 2.The structure was refined to R = 0.0288 for 1131 observed reflections (F_o > 4?(F_o)).
