,η3-Allyl and similar complexes,n ligand of this type. However, one should bear in mind that Ln-η.-R complexes even in solid state have a tendency to be transformed in to the Ln-η.-R form [1]. Thereat the rest of substituents at the lanthanoid atom has essential influence on the character of the Ln-allyl bond. For example, in the

Compounds with lanthanoid-metal bonds,compounds with bridging atoms or groups (H, Cl, R, OR, SR) between the Ln and M atoms as well as the REM compounds, in which the M atom is incorporated into an organic ligand, belong to the first of these groups. Distinctive features of such compounds are determined in general by the nature of ligan

Complexes of Ce(IV),vatives were described, including cyclopentadienyl, indenyl, fluorenyl, cycloheptatrienyl and cyclooctatetraenyl complexes (Table XI.1.). The structure of compounds was confirmed in the most cases by the data of elemental analysis (C, H, Ce), IR spectroscopy and chemical reactions. At the same time
