Lanthanide(II) complexes bearing mixed linked and unlinked cyclopentadienyl–monodentate-anionic ligands
摘要:
This paper is intended to provide an overview on recent progress in the chemistry of divalent lanthanide complexes bearing mixed (linked and unlinked) cyclopentadienyl-monodentate-anionic ligands. The synthesis, structures, and one-electron-transfer and polymerization reactions of these complexes are described. (C) 2002 Elsevier Science B.V. All rights reserved.
