Much more versatile than previously anticipated are the coordination modes of tris(pyrazolyl)borate ligands (scorpionates). Recent contributions in this area not only lead to a new understanding of the electronic effects, but for the first time report unusually high and low hapticities as well as novel coordination modes such as the π coordination of a pyrazolyl ring to potassium (see structure). Potentially useful new ligands have been made available through innovative synthetic routes.
