Abstract
The (1,3-(Bu2C5H3)-C-t)(2)Eu . THF complex was prepared by the reaction of 1,3-(Bu2C5H3Na)-C-t with EuI2 in tetrahydrofuran. The mixed-ligand (1,3-(Bu 2C5H3)-C-t)(C5Me5)Yb . THF complex was obtained by the reaction of YbI2 wit h C5Me5Na and 1,3-(Bu2C5H3Na)-C-t. The reaction of 1,3-(Bu2C5H3Li)-C-t with YbCl3 afforded the (1,3-(Bu2C5H3)-C-t)(2)Yb(mu(2)-Cl)(2)Li(THF)(2) ate-com plex. The structures of the title compounds were established by X-ray diffr action analysis.
