    • The spin densities of 3.5 on each iron center are indicative of high-spin (S = 2) configurations. A second reasonable possibility is an intermediate-spin (S = 1) state with only half of the four d-electrons unpaired on each metal center. A recent computational study (ref 55) has shown that the S = I spin state of the antiferromagnetically coupled Q is 7.53 kcal/mol higher in energy than the S = 2 state. This result is in good agreement with typical values found in exploratory calculations for our large-scale model. Thus. this alternative is not further considered.

    • This interesting relationship between structure and reactivity might be an exploitable design feature. A more detailed quantitative analysis of the chemical difference between O3 and O4 is not helpful for this paper and will be presented elsewhere together with a possible exploitation strategy in synthetic models.
