Abstract

Some underreported aspects of polypyrazolylborate chemistry are explored, in particular novel lanthanide coordination chemistry and zwitterionic ligand replacements of this so-called "scorpionate" class of ligands.  The application of these ligands to future materials engineering is postulated and, finally, the historic relevance of the topic to L'viv is described.
