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 [phenazineF].+ as the [Al(ORF)4]− and [F‐{Al(ORF)3}2]− salt (RF=C(CF3)3; phenazineF=perfluoro‐5,10‐bis(perfluorophenyl)‐5,10‐dihydrophenazine). [Fe(CO)5].+[Al(ORF)4]− was fully characterized (scXRD analysis, IR, NMR, EPR, 57Fe 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.
