Mössbauer, EPR and DFT Studies of Synthetic S = ½ Fe(III)-O-Fe(IV)=O Complexes. Superexchange-Mediated Spin Transition at the Fe(IV)=O Site

Previously we have characterized two high-valent complexes [LFe(IV)(µ-O)(2)Fe(III)L], 1, and [LFe(IV)(O)(O)(OH) Fe(IV)L], 4. Addition of hydroxide or fluoride to 1 produces two new complexes, 1-OH and 1-F. EPR and Mössbauer studies show that both complexes have an S = ½ ground state which results fr...
