文摘

The Pd(I)鈭扨d(I) dimer [(^FPNP)Pd鈭抅₂ reacts with O₂ upon exposure to light to produce either the superoxide (^FPNP)PdO₂ or the peroxide [(^FPNP)PdO鈭抅₂, which exist in equilibrium with free O₂. Both complexes contain square-planar Pd(II) centers. The unpaired electron density in (^FPNP)PdO₂ is localized on the superoxide ligand.
