Abstract

Two novel 1D and 2D polyoxometalate (POM) frameworks based on the new Zn2Sb2(B-alpha-ZnW9O34)(2)](14-) building block were selectively obtained from one-pot transformations of the trilacunary Keggin-type B-alpha-SbW9O33](9-) precursor via Sb/Zn exchange, followed by self-assembly of the sandwich-type polyanions. The compounds were characterized in detail with a wide range of analytical methods, including single crystal and powder X-ray diffraction, thermogravimetric analysis and various spectroscopic techniques, and their photoluminescence properties were investigated at room temperature. Electrochemical behavior of the 1D and 2D {Zn2Sb2}-based POMs was characterized by means of cyclic voltammetry (CV) in sodium acetate buffer solution. Both compounds are effective catalysts for the oxidation of cyclohexanol with hydrogen peroxide.
