Tetrakis(benzyltriethylammonium) octamolybdate

M.-L. Guo, C.-H. Guo, H.-Z. Li and H. Chang

Abstract: The asymmetric unit of the title compound, (C₁₃H₂₂N)₄[Mo₈O₂₆], comprises four independent benzyltriethylammonium cations and two independent Mo₄O₁₃ units. These latter units lie about inversion centres which generate two complete Mo₈O₂₆^4- anions in the -isomeric form. Four discrete sets of Mo-O bond distances are found in the octamolybdate anions corresponding to terminal and 2-, 3- or 5-bridging situations. In the crystal structure, an extensive array of weak intermolecular C-HO hydrogen bonds stabilizes the crystal packing.
