One-electron reduction of a pyrazolate-bridged triangular Fe (μ -O) core induces a cascade wherein all three metal centers switch from high-spin Fe to low-spin Fe . This hypothesis is supported by spectroscopic data ( H-NMR, UV-vis-NIR, infra-red, Fe-Mössbauer, EPR), X-ray crystallographic characterization of the cluster in both oxidation states and also density functional theory. The reduction induces substantial contraction in all bond lengths around the metal centers, along with diagnostic shifts in the spectroscopic parameters.
