Abstract

original image

Easy to synthesize and highly soluble are the new (1,4-diaza-1,3-diene) complexes 1 and 2, which can be considered as alternative starting materials to the frequently used cyclopentadienyl lanthanoid halides in organolanthanoid chemistry. The similarity of Cp ligands and the [(dad)Li]- unit is apparent in the structure of 1 on the right; complexes 2 have a different structure as a result of the smaller ionic radius of the lanthanoid.
