(Received 7 November 2012; accepted 14 November 2012; online 24 November 2012)

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.

Comment top

Transition-metal oxofluoride hybrids have been intensively studied due to their interesting magnetic, optical and electrochemical properties (Nakajima et al., 2000). This paper presents a new organic-inorganic hybrid compound with molybdenum (V) and 1,4-butanediamine. To date, few hybrid oxofluoromolybdates (V) are reported in the literature. [MoOF₅]^2- monomers, [Mo₂O₂F₉]^3- and [Mo₂O₄F₆]^4- dimers were obtained with ammonium by Mattes et al. (1976, 1980). Adil et al. (2007) reported the previous monomer with tren cations. Two other compounds, built up from [Mo₂O₄F₄]^2- dimers with bipyridinium or phenanthrolinium, were synthesized by Chakravorti et al. (1983). It must be noted that the same author obtained many alkali metal molybdenum (V) complexes; their structures involve [MoOF₅]^2-, [Mo₂O₄F₄]^2-, [Mo₂O₄F₅]^3- and [Mo₂O₄F₆]^4- anions. Recently, a novel tetrameric unit [Mo₄O₈F₁₀]^6- was observed in (NH₄)₆[Mo₄O₈F₁₀] and K₆[Mo₄O₈F₁₀] (Aldous & Lightfoot, 2012).

The structure of a new oxofluoride molybdate [H₂dab]₂.(Mo₂O₄F₆).H₂O, synthesized in the MoO₃-dab-HF_aq-water-ethylenglycol system, is here described. It is built up from [Mo₂O₄F₆]^4- dimers, diprotonated (H₂dab)²⁺ cations and water molecules (Fig. 1). The Mo₂O₄F₆ unit is formed by two MoO₃F₃ octahedra connected by one O–O edge. The MoO₃F₃ octahedron is strongly distorted due to the presence of two types of Mo–O bonds: one short bond for the terminal O atom and two medium-ranged bonds for the bridging O atom (Table 1). The Mo–F and Mo–O distances are in good agreement with literature values (Mattes et al., 1980; Adil et al., 2007). Isolated water molecules are hydrogen bonded in a tetrahedral geometry with two –NH₃ cations and two fluorine atoms (Fig. 2). The inorganic anions and organic cations are connected by intermolecular hydrogen bonds (Fig. 3 and Table 2), creating a two-dimensional network of hydrogen bonds parallel to (-102) between the inorganic anion sheets and organic cation layers.

Experimental top

The starting chemical reactants were molybdenum trioxide (MoO₃), 1,4-diaminobutane, aqueous HF (48%), water and ethylenglycol in the molar ratio 1:20:55:278:103. The starting mixture was dissolved under solvothermal conditions at 170°C for 72 h. Single crystals were obtained after the evaporation of the solution at room temperature. Crystals suitable for X-ray diffraction were selected under a polarizing optical microscope.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
