title: Photoinduced water oxidation catalyzed by a double-helical dicobalt(II) sexipyridine complex.
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 functions as a molecular catalyst and does not produce any CoOx in water oxidation.
