suggested for the titaniumcomplexes, while distorted octahedral geometries with a κ3-N,N,O coordination are proposed for the zirconium derivatives. Fluxional exchange between coordinated and non-coordinated pyrazolate rings is concluded in some zirconium compounds, depending on the electronic and steric effects imposed by the substituents of the heteroscorpionate ligands. Preliminary studies of catalytic
