Aspects of non-classical organolanthanide chemistry

This paper provides a survey of our studies on: (i) subvalent compounds of lanthanum and early 4f elements; (ii) cationic mononuclear samarium(II) and ytterbium(II) organic complexes; (iii) low valent samarium and ytterbium β-diketiminates; and (iv) mononuclear cerium(IV) amides and a mixed valence trinuclear Ce(IV)/Ce(III) cluster. A brief introductory section points to our earlier (1973–1995) studies on organo-4f-element chemistry.
