Abstract

[Mn3SrO4] cluster compounds are synthesized in a single step from raw materials consisting of simple and inexpensive Mn2+, Sr2+ inorganic compounds and carboxylic acids by using permanganate anion as oxidant. This step can be followed by the synthesis of asymmetric biomimetic water splitting catalyst [Mn4SrO4] cluster compounds in the presence of water. The [Mn4SrO4] cluster compound can catalyze the splitting of water in the presence of an oxidant to release oxygen gas. The neutral [Mn3SrO4](R1CO2)6(R1CO2H)3 cluster compound can serve as precursors for the synthesis of biomimetic water splitting catalysts, and can be utilized in the synthesis of different types of biomimetic water splitting catalysts. [Mn4SrO4](R1CO2)8(L1)(L2)(L3)(L4) cluster compounds can serve as artificial water splitting catalysts, can be utilized on the surface of an electrode or in the catalyzed splitting of water driven by an anoxidant.
