Characterization of the Terminal Iron(IV) Imides {[PhBPtBu2(pz')]FeIV⋮NAd}+
New hybrid bis (phosphine)(pyrazole) borate tripodal ligands ([PhBP t Bu2 (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.
