    • As a reviewer noted, a diamagnetic species could conceivably also arise from an antiferromagnetically coupled Mn(IV)-O-Mn(IV) dimer. Although this is possible, we observed no EPR signal even down to 6 K. Also, we feel that we can exclude this assignment of the narrow peaks because the diamagnetic species is not persistent in the presence of oxygen acceptors (substrates), although one would expect the opposite for a Mn-(IV)-O-Mn(IV) dimer; it should be quite stable in solution. Furthermore, one would expect the Mn(IV)-O-Mn(IV) dimer to be a poor oxygen donor especially since it has already been shown that even monomeric Mn(IV)-O species are not reactive (ref 10).
