All important properties of coordination compounds – hermodynamics (complex stabilities, metal ion selectivities, redox potentials), kinetics (reaction rates, selectivities and pathways) as well as electronics (spectroscopy and magnetism) – depend on their structure. The structure of metal complexes is the result of metal ion and ligand preferences, and it is shown that ligand preferences prevail, especially with ligands as rigid as the bispidines. The unique geometries of bispidine transition metal and lanthanide complexes will be described and the resulting properties will be discussed. Specific examples and applications that will be presented include the CuII/I couple with applications ranging from oxygen activation, azidirination and positron emission tomography (PET) and high-valent nonheme iron model chemistry (oxidation catalysis).
