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. Кеуwordsscorpionates, scorpionate ligands, polypyrazolylborates, polypyrazolylborate ligands, Trofimenko, Swiatoslaw, materials engineering, lanthanide ions.
