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