Synthesis, Crystal Structure And Properties Of Microporous, Rare Earth Compound Based On Heteropolymolybdates Structrue Building Blocks

This paper mainly includes two parts. The first part: on the basis of molecular assembly, a series of porous compounds were successfully synthesized in aqueous (or mixed solvent) by the reaction of Keggin anions [XMo₁₂O₄₀]^n- (X = Si^â…£, Ge^â…£, n = 4; X = P^â…¤, n = 3) and macrocations [M₃O(OOCR)₆(H₂O)₃]⁺ (M = Fe^â…¢, Cr^â…¢; R = CH₃,C₂H₅), which were characterized by X-ray crystallography, IR, UV/Vis, XPS and thermal properties. The second part: a series of polyoxometalates based on B-Anderson anions [CrMo₆O₂₄H₆]^3- are successfully synthesized in aqueous. The compounds were characterized by X-ray crystallography, IR, UV/Vis, electrochemical and luminescent properties.
