Ligand Design and Geometry Control in Electroactive Heterospin Precursors for Magnetic Switching. Claudio N. Verani - Wayne State University We are developing five-coordinated complexes capable of enhancing the formation, Stabilization, and cycling of phenoxyl radicals. These species are prototypical precursors for responsive films and will become useful in the development of molecule-based devices for information storage. The [CuFe] Complex:
