Amazingly stable : The bis(guanidine) ligand N 1 , N 3 ‐bis[bis(2,2,6,6‐tetramethylpiperidin‐1‐yl)methylen]propan‐1,3‐diamine stabilizes the first bis(μ‐oxo)dicopper(III) complex (see figure) at room temperature. This complex is characterized in the ground state and in the optical excited state by a combination of EXAFS and resonance Raman spectroscopy.
