A spectral study of the interaction of dioxygen with sublimed layers of manganese(II) meso-tetraphenylporphyrinate

Article abstract of DOI:10.1007/BF02495157

The low-temperature interaction of sublimed layers of manganese(II) meso-tetraphenylporphyrinate (MnTPP) with O₂, which has previously been observed only in solutions and in an inert gas matrix, was found by electron absorption and IR spectroscopy. The coordination of O₂ with sublimed MnTPP layers is only partially reversible. Bands that can serve as IR-spectral markers characteristic of the high-spin Mn¹¹ ion in MnTPP and its axial complexes were observed.
