A Water-soluble Ni Dihydrido Complex That Reduces O-2 to H2O in Water
We report the first example of reduction of O-2 to H2O by a Ni(II) dihydrido species. Isotope-labeling experiments reveal a four-electron reduction of O-2 by the dihydrido species. The water-soluble Ni(II) dihydrido species was characterized by X-ray analysis, electrospray ionization mass spectrometry, and IR, H-1-INMR, ESR, and UV-vis spectroscopies.
