Abstract
New hybrid bis(phosphine)(pyrazole)borate tripodal ligands ([PhBPtBu2(pz‘)]-) are reported that support pseudotetrahedral iron in the oxidation states +1, +2, +3, and +4. The higher oxidation states are stabilized by a terminal Fe⋮NR linkage. Of particular interest is the generation and thorough characterization of an S = 1 FeIV⋮NR+ imide cation using this new ligand system. The latter species can be observed electrochemically and spectroscopically, and its solid-state crystal structure is reported.Keywords
