In the structure of the title salt, 2C3H5N2+·C6H8O82−·2H2O, the galacta­rate dianions have crystallographic inversion symmetry and together with the water mol­ecules of solvation form hydrogen-bonded sheet substructures which extend along (110). The imidazolium cations link these sheets peripherally down c through carboxyl­ate O—H—N and N′—H⋯Ohy­droxy bridges, giving a three-dimensional framework structure.

Comment top

Galactaric acid (mucic acid) (O'Neil, 2001) is the C6 homologue of tartaric acid but differs from it in being achiral and as well has only a small number of representative crystal structures in the CSD, e.g. the acid itself (Jeffrey & Wood, 1982), ammonium hydrogen galactarate (Bontchev & Moore, 2005), diammonium galactarate (Benetollo et al., 1993) and some metal complexes, e.g. copper(II) galactarate dihydrate (a fungicide) (Ferrier et al., 1998). Because the imidazolium cation has proved to be an excellent linking molecule for the generation of supramolecular layered structures particularly with dicarboxylic acids, including hydroxy acids (James & Matsushima, 1976; MacDonald et al., 2001; Aakeröy & Hitchcock, 1993; Fuller et al., 1995; Fukunaga & Ishida, 2003; Trivedi et al., 2003), we carried out a 1:2 stoichiometric reaction of galactaric acid with imidazole in aqueous ethanol and obtained large relatively hard, chemically stable crystals of the title compound, 2(CH6N3+) C6H8O82-. 2H2O (I), and the structure is reported here.

In the structure of (I) (Fig. 1), the galactarate anions lie across crystallographic inversion centres which is also the case in the structure of the parent acid (Jeffrey & Wood, 1982). Hydrogen-bonded anion-water sheets extending across the <100> planes in the unit cell (Fig. 2) are formed through hydroxyl O31–H···O12iiicarboxyl and water-bridging O31···O11ivcarboxyl interactions (for symmetry codes, see Table 1). These include R22(12) and R33(12) cyclic motifs (Etter et al., 1990). The layered substructures are linked peripherally down the c cell direction by the imidazolium cations through carboxyl O···H—N,N'—H···O`hydroxyl bridges giving a three-dimensional framework structure (Fig. 3). The structure of (I) differs from those of the anhydrous 1:1 salts of the hydrogen dicarboxylates (MacDonald et al., 2001) in which the bridging imidazolium cations are incorporated within two-dimensional layered structures.

Experimental top

The title compound was synthesized by heating together under reflux for 10 minutes 1 mmol of galactaric acid (mucic acid) and 2 mmol of imidazole in 50 ml of 50% ethanol-water. After concentration to ca 30 ml, partial room temperature evaporation of the hot-filtered solution gave large colourless plates of (I) (m.p. 435 K) from which a suitable analytical specimen was cleaved.

Refinement top

Hydrogen atoms potentially involved in hydrogen-bonding interactions were located by difference methods and their positional and isotropic displacement parameters were refined. Other H atoms were included in the refinement in calculated positions (C–Haromatic = 0.95 Å and others = 1.00 Å) and allowed to ride, with Uiso(H) = 1.2Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
