摘要:
The Pd(I)-Pd(I) dimer [((PNP)-P-F)Pd-](2) reacts with O-2 upon exposure to light to produce either the superoxide ((PNP)-P-F)PdO2 or the peroxide [((PNP)-P-F)PdO-] 2, which exist in equilibrium with free O-2. Both complexes contain square-planar Pd(II) centers. The unpaired electron density in ((PNP)-P-F)PdO2 is localized on the superoxide ligand.
