Complexes with Nitroxides Containing Different Substituents in the Alpha-Position to N-Center-Dot-O Group - Competition of Basicity and Sterical Availability of the Donor Functions of Nitroxides in Metal-Complexes with Sterically Hindered Imidazolines
In the nitroxide molecule, change of the substituent in the alpha-position to the N .-O group affects both the donor properties of this group and its steric availability. Metal complexes with three nitroxide pairs are used to show that the above change of the alpha-substituent in the nitroxide molecule can induce structural transformation of the molecular complex itself(and, as a consequence, change its magnetic properties), change the magnetic properties of the solid complex, or change the chemical behavior of the nitroxide.
