Bis(butane-1,4-diammonium) di-μ-oxido-bis[trifluoridooxidomolybdate(V)] monohydrate

The title compound, (C₄H₁₄N₂)₂[Mo₂O₄F₆]·H₂O, was obtained by solvothermal reaction at 443 K for 72 h from a mixture of MoO₃, HF, 1,4-diamino­butane (dab), water and ethyl­ene glycol. The structure consists of [Mo₂O₄F₆]⁴⁻ anionic dimers containing strongly distorted MoO₃F₃ octa­hedra (with twofold symmetry), diprotonated dab cations and water mol­ecules (twofold symmetry) in the ratio 1:2:1. The cohesion of the three-dimensional structure is ensured through N—H...O, N—H...F and O—H...F inter­actions.
