Dalton communications. Models of cytochromes b containing an organometallic axial base, azaferrocene: synthesis and electron paramagnetic resonance study
Abstract
Azaferrocene reacted with [Fe(oep)(O3SCF3)] or [Fe(tpp)(O3SCF3)](oep = 2,3,7,8,12,13,17,18-octaethylporphyrinate; tpp = 5,10,15,20-tetraphenylporphyrinate to afford [Fe(oep){Fe(C5H5)(C4H4N}2]O3SCF3 or [Fe(tpp){Fe(C5H5)(C4H4N)}2]O3SCF3, respectively; the trinuclear complexes exhibit rhombic low-spin EPR spectra indicating the strong ligating ability of azaferrocene.
