18. A Cu⋯Fe vector at 3.59(2) Å could be included in the fits; however, this did not lead to a statistically better or worse refinement.
19. Five-coordinate Fe porphyrin oxo and chloro complexes display an enhanced Fe(1s)→Fe(3d) transition because of the strong axial interaction along the molecular z-axis, which allows for 4p mixing into the d-manifold, and hence a "less disallowed" transition.
