RECENT ADVANCES IN THE CHEMISTRY OF F-ELEMENT POLY(PYRAZOLYL)BORATE COMPLEXES

This paper presents an overview of the chemical progress involving f-e lements and poly(pyrazolyl)borate ligands. This includes compounds of lanthanides(III) and (II) and actinides(IV) and (III). Because of its close similarity, yttrium is also included. The synthetic, chemical, s tructural, and solution behaviors of these compounds are reviewed. The plan of the review is: 1. Introduction 2. Synthetic and chemical aspe cts 2.1 Lanthanides(III) 2.2 Lanthanides(II) 2.3 Actinides(IV) 2.4 Act inides(III) 3. Structural aspects and solution behavior 4. Concluding remarks 5. Abbreviations and references.
