Regarding the spin density distribution, the Cu center displays values of 0.6 a.u. in agreement with other works related to the magnetic properties of Cu(II) complexes (showing one unpaired electron) . Besides, the spin density surface (Fig. ) is located mainly on the CuC core, and the surface shape resembles the 3dx2-y2 orbitals as is proper of Cu(II) center in a square-planar ligand field . In this sense, part of spin density is localized onto Cu(II). In contrast, the resting spin density is delocalized along with the corrole core showing a non-innocent and magnetic character.
