Hydrothermal Synthesis and Physicochemical Characterization of Organic-Inorganic Isopolyoxomolybdate-Based Hybrid (C6N6)4[H4Mo8O26]

详细

A novel polyoxomolybdate-based organic-inorganic hybrid compound, (C₆H₆)₄[H₄Mo₈O₂₆], has been synthesized hydrothermally and characterized structurally by the elemental analysis, single crystal X-ray diffraction, thermogravimetric analysis, infrared and ultraviolet–visible spectroscopies, and cyclic voltammetry. Crystallographic data for the compound are: triclinic system, space group \(P\mathop 1\limits^\_ \), unit cell parameters a = 9.605(2)  Å, b = 9.991(3) Å, c = 10.718(3) Å, α = 83.75(2)°, β = 76.45(3)°, γ = 69.07(3)°, Z = 1. The crystal consists of the clusters β-[Mo₈O₂₆]^4– and four organic molecules C₆H₆. Isopolymolybdate anions are connected with the organic molecules via a complex hydrogen-bonded network, which generate a three-dimensional framework.
