Аннотация

Novel supramolecular networks based on an anionic polymolybdophosphate cluster Sr10(H2O)12[Sr2P9HMo12O71] is hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction, thermogravimetric analysis, infrared, ultraviolet spectroscopy, and cyclic voltammetry in an aqueous solution. It crystallizes in the orthorhombic space group Pnmm (No. 59) with a = 12.699(1), b = 14.914(1), c = 23.851(2) Å and Z = 2. The compound is made up of unusual shaped-cage [Sr2P9HMo12O71]20-. The strontium cations are divided in two kinds. The first occupy vacant sites in the [P9Mo12O68] n- polyoxoanions unit and the second [Sr(H2O)6]2+, [Sr(H2O)4]2+, and [Sr(H2O)2]2+ serve to bridge together the adjacent polymolybdophosphate clusters to yield unprecedented three-dimensional pure inorganic assemblies of the shaped-cage polymolybdophosphate clusters.
