摘要：

Ytterbium complexes, Cp(2)Yb(mu-eta(2):eta(2)-DAB)Li(DME) (1) and CpYb(DAB)K(THF)(2) (2), containing a bridging diazadiene ligand were prepared by the reaction of CpYbCl(2)(THF)(3) with (DAB)Li-2 (1:1) and (DAB)K--(+) (1:2) (DAB = Bu(t)-N=CH-CH=N-Bu(t)). The structure of complex 1 was established by X-ray diffraction analysis. The complex is binuclear: the Yb atom of the Cp(2)Yb fragment and the Li atom, which is bonded as well with the chelating DME molecule, are linked by the DAB ligand.
