Tris(ethyl­enediammonium) bis­(2-amino­ethyl)ammonium bis­bis­(μ5-hydrogen phosphato)penta-μ2-oxido-deca­oxido­penta­molybdenum(VI) deca­hydrate

摘要

The title compound, (C2H10N2)3(C2H9N2)2[Mo5(HPO4)2O15]·10H2O, was prepared under hydro­thermal conditions at pH 5.0. The structure contains mono- and diprotonated ethyl­enediamine cations, [Mo5O15(HPO4)₂]⁴⁻ anions and uncoord­in­ated water mol­ecules. The [Mo₅O₁₅(HPO₄)₂]⁴⁻ hetero­poly­oxometallate anion is made up of five MoO₆ octa­hedra sharing an edge and forming a ring, which is closed by common corners of the terminal MoO₆ octa­hedron. The ring is topped on both sides by two slightly distorted PO₄ tetra­hedra, sharing three corners with three MoO₆ octa­hedra. The terminal oxygen atoms of the PO₄ units are protonated. Together with the anions, the water mol­ecules and the ethyl­enediammonium cations are involved in N—H⋯O and O—H⋯O hydrogen bonding, forming a three-dimensional supra­molecular network.
