Poly[tris(p-xylylenediaminium) [tetradeca--oxo-hexadecanonamolybdate(VI)] dihydrate]

Abstract: Crystals of the title compound, {[C₈H₁₄N₂]₃[Mo₉O₃₀]·2H₂O}_n, were grown under mild hydrothermal conditions in the presence of p-xylylenediamine. [Mo₉O₃₀]_n^6n- chains, constructed from [MoO₆] octahedra and [MoO₄] tetrahedra, are separated by protonated p-xylylenediaminium cations and occluded water molecules, creating an extensive hydrogen-bonding network. One cation posseses a centre of symmetry; the anion is also centrosymmetric and one Mo atom lies on a crystallographic twofold rotation axis.
