Abstract
The aerobic reaction of Cr(CO)(6) with tris(pentafluorophenyl)corrole (H-3( TpFPC)) in toluene gives the dark red oxochromium(V) compound (TpFPC)Cr(O), which has been characterized by X-ray crystallography, electrochemistry, a nd EPR spectroscopy. Short Cr-N (1.927-1.943 Angstrom) bonds as well as rel atively large N-14 and small Cr-53 coupling constants suggest that sigma(N --> Cr) donation is responsible for the unusual stability of chromium(V) in this complex. The Cr-V/IV reduction potential (0.11 V vs Ag/AgCl) is 0.65 V below that of oxo(tetra-mesitylporphinato)chromium(V).
