Evidence for tetranuclear bis-µ-oxo cubane species in molecular iridium-based water oxidation catalysts from XAS analysis
Evidence for tetranuclear bis-µ-oxo cubane species in molecular iridium-based water oxidation catalysts from XAS analysis
The structure of a highly active pyridine-alkoxide iridium water oxidation catalyst (WOC) is examined by X-ray absorption spectroscopy (XAS). A detailed comparison with IrO2 points to a rigid molecular unit of low nuclearity, with the best analysis suggesting the existence of a novel tetrameric iridium-oxo cubane as the resting state.

Abstract
The structure of a highly active pyridine-alkoxide iridium water oxidation catalyst (WOC) is examined by X-ray absorption spectroscopy (XAS). A detailed comparison with IrO2 points to a rigid molecular unit of low nuclearity, with the best analysis suggesting the existence of a novel tetrameric iridium-oxo cubane as the resting state.
