Abstract

A double-helical dicobalt(ii) complex [Co₂(spy)₂](ClO₄)₄ (spy = 2,2′:6′,2′:6′,2‴:6‴,2⁗:6⁗,2⁗′-sexipyridine) (1) is found to catalyze visible light-induced water oxidation by [Ru(bpy)₃]²⁺/Na₂S₂O₈, with a maximum turnover number of 442. Several lines of evidence suggest that 1 functions as a molecular catalyst and does not produce any CoO_x in water oxidation.
