Abstract

Oxoferrylporphyrin cation radical complexes were generated using the prophyrin dianions: tetrakis 2,6-dichlorophenyl (TDCPP) and tetrakis 2,4,6-trimethoxyphenyl (TTMPP). Spin coupling between ferryl iron (S=1) and porphyrin radical S′=1/2), ligand field interaction and hyperfine parameters of iron were studied by Mössbauer and EPR measurements and corresponding spin Hamiltonian analyses. Samples of [Fe^IV=0 TDCPP], which had to be prepared in CH₂Cl₂, were "vacuum dried" in order to obtain Mössbauer spectra.
