Metal-nitroxyl interactions. 50. EPR spectra of high-spin iron(III) complexes of spin-labeled tetraphenylporphyrins in fluid solution

EPR spectra were obtained for a series of high-spin iron(III) complexes of spin-labeled tetraphenylporphyrins (P) in fluid solution. Iron EPR signals were observed at room temperature for the spin-labeled complexes and for high-spin iron(III) complexes of tetratolylporphyrin with chloride, fluoride, and dimethyl sulfoxide as the axial ligands. In the complexes with weak iron-nitroxyl interaction the iron relaxation rate was sufficiently fast to collapse the electron-electron spin-spin splitting of the nitroxyl signal. As the strength of the iron-nitroxyl spin-spin interaction increased, the nitroxyl signal broadened and moved to a higher g value. For two of the complexes the iron-nitroxyl interaction was sufficiently strong to cause averaging of the iron ±1/2 and nitroxyl transitions.
