Through a combination of X-ray crystallography, optical and NMR spectroscopies, SQUID magnetometry, and density functional theory calculations, detailed molecular and electronic structure descriptions of a previously reported iron(II) o-semiquinonate complex and two new nickel(II) o-semiquinonate complexes were obtained. Studies of the O2 reactivity of these complexes led to the discovery of the first synthetic iron(II) o-semiquinonate species exhibiting intradiol cleaving reactivity. These studies highlight the fundamental effect of the metal ion on the intradiol cleaving reactivity.
