respectively. . Each of the configurations differs with the occupancy of d z 2 +π L and d z 2π L . The dominant configuration with 51% contribution has two electrons in d z 2 +π L . The configuration with 18% contribution has two electrons in d z 2 -π L . In the remaining two configurations, there is one α and one β in the two orbitals. The radical character using Eq. 2 and 3 is calculated to be 60% that is higher than that of Fe is occupied with two electrons (Table ). In a similar way, we quantified the extent of electron transfer from Ph ring to the Mn using Eq. 2 and 3. It results in a combination of 80% Mn(IV) and 20% Mn(III) oxidation state in the complex. Mn[Cor]py is a single determinant system with 97% electronic configuration (Table ). Further, the XANES spectra plotted from MC-PDFT for all the Mn metallocorroles are shown in Figure .
