The Pd(I)-Pd(I) dimer ((F)PNP)Pd- reacts with O(2) upon exposure to light to produce either the superoxide ((F)PNP)PdO(2) or the peroxide ((F)PNP)PdO-, which exist in equilibrium with free O(2). Both complexes contain square-planar Pd(II) centers. The unpaired electron density in ((F)PNP)PdO(2) is localized on the superoxide ligand.
Pd(I)-Pd(I)二聚体 ((F)PNP)Pd- 在光照下与 O(2) 反应，生成超氧化物 ((F)PNP)PdO(2) 或过氧化物 ((F)PNP)PdO-，两者与游离 O(2) 处于平衡状态。这两个配合物都含有平面正方形的 Pd(II)中心。在 ((F)PNP)PdO(2) 中，未成对电子密度定域在超氧配体上。
