Three Distinct Oxidation States (II/II, II/III, and III/III) of Diorganocopper Complexes.

ABSTRACT: In this report, we present a structurally and spectroscopically characterized diorganocopper system in three distinct oxidation states: [Cu^IICu^II] (1), [Cu^IICu^III] (2), and [Cu^IIICu^III] (3). These states are stabilized by a macrocyclic ligand scaffold featuring two square-planar coordination {C₂ ^NHCN₂ ^pyrazole}. We have analyzed the geometric and electronic structures using X-ray diffraction (XRD) and multiple spectroscopic methods including nuclear magnetic resonance (NMR), UV-vis, and electron paramagnetic resonance (EPR) spectroscopies, in combination with density functional theory (DFT) calculations. Remarkably, this study provides a structural determinatio
