Abstract

Analysis of the ¹H and ¹³C NMR chemical shifts has revealed that bis-ligated iron(III) porphyrinates, [Fe(Porphyrin)(L)₂]^±, adopt the (d_xz, d_yz)³ (d_xy)¹ (d_z2)¹ ground state if the complex has highly ruffled porphyrin core and carries weak oxygen ligand with multiple bond such as benzaldehyde.
