Facile one-pot synthesis of hybrid compounds based on decavanadate showing water oxidation activity

Abstract Herein, we report the synthesis of two hybrid compounds based on decavanadate anion, namely, [Cu(dien)(Hdien)]2[V10O28]·2H2O (1) and (H3dien)2[V10O28]·4H2O (2), where dien = diethylenetriamine, obtained under mild conditions. Both compounds were characterized by elemental, TG/DTA, single crystal and powder X-ray diffraction analyses, IR and EPR spectroscopies. The compound 1 was found to be active as homogeneous photochemical oxidation catalyst of water to dioxygen.
