Synthesis and Characterization of Stable Iron Pentacarbonyl Radical Cation Salts

The open‐shell iron pentacarbonyl cation [Fe(CO)(5)](.+) was isolated by deelectronation, i.e., the single‐electron oxidation of the parent neutral Fe(CO)(5) using [phenazine(F)](.+) as the [Al(OR(F))(4)](−) and [F‐{Al(OR(F))(3)}(2)](−) salt (R(F)=C(CF(3))(3); phenazine(F)=perfluoro‐5,10‐bis(perfluo...

description The open‐shell iron pentacarbonyl cation [Fe(CO)(5)](.+) was isolated by deelectronation, i.e., the single‐electron oxidation of the parent neutral Fe(CO)(5) using [phenazine(F)](.+) as the [Al(OR(F))(4)](−) and [F‐{Al(OR(F))(3)}(2)](−) salt (R(F)=C(CF(3))(3); phenazine(F)=perfluoro‐5,10‐bis(perfluorophenyl)‐5,10‐dihydrophenazine). [Fe(CO)(5)](.+)[Al(OR(F))(4)](−) was fully characterized (scXRD analysis, IR, NMR, EPR, (57)Fe spectroscopy, CV and SQUID magnetization study) and, apart from being a compound of fundamental interest, may serve as a precursor for low‐valent iron coordination chemistry.
