The title compound, Na+·C5H11O8S− [systematic name: sodium (1S,2S,3S,4R)-1,2,3,4,5-pentahydroxypentane-1-sulfonate], is formed by reaction of D-lyxose with sodium bisulfite (sodium hydrogen sulfite) in water. The anion has an open-chain structure in which one of the oxygen atoms of the sulfonate residue, the S atom, the C atoms of the sugar chain and the O atom of the hydroxymethyl group form an essentially planar zigzag chain with the corresponding torsion angles lying between 179.80 (11) and 167.74 (14)°. A three-dimensional bonding network exists in the involving hexacoordination of sodium ions by O atoms, three of which are provided by a single D-lyxose–sulfonate unit and the other three by two sulfonate groups and one hydroxymethyl group, each from separate units of the adduct. Extensive intermolecular O—H⋯O hydrogen bonding supplements this bonding network.
Keywords: crystal structure; D-lyxose bisulfite adduct; sodium hydrogen sulfite; sodium metabisulfite.

1. Chemical context
Bisulfite adducts of et al., 2013) has focused on counter-ion effects in the preparation of aldehyde–bisulfite adducts. Of particular concern in that work was a comparison of the physical properties of sodium and potassium bisulfite adducts of a range of to include their hygroscopic nature and ease of filtration, in order to facilitate their preparation and storage on a large scale. Studies by X-ray crystallography on the bisulfite adducts of common aldehydo-sugars such as D-glucose (Cole et al., 2001) and our related work on D-galactose (Haines & Hughes, 2010), D-ribose (Haines & Hughes, 2014) and D-lyxose (Haines & Hughes, 2015) indicated the crystallinity and ease of isolation of such potassium adducts, and also, in the case of the sodium bisulfite adduct of D-glucose (Haines & Hughes, 2012), allowed a comparison of the potassium and sodium compounds. We now report the preparation (Fig. 1), properties, and of the sodium bisulfite adduct of D-lyxose, which allows a further comparison of the influence of the two counter-ions in the properties of an adduct from the same substrate.
are important compounds because, in many cases, they are crystalline and allow a means of purification and storage of those which are liquids or which suffer from problems of instability. The importance of in many synthetic processes for the production of commercially important compounds, including pharmaceuticals, means that there is continuing interest in these bisulfite adducts. A recent publication (KissaneCrystallization of the sodium bisulfite adduct of D-lyxose from water required a very concentrated solution from which highly crystalline material grew slowly on storage at room temperature. In contrast to the potassium adduct (Haines & Hughes, 2015), the crystals lacked water of crystallization but had the same S-configuration at C1, leading to a similar positive for the two products. The melting points of the sodium and potassium adducts (417.6–420.1 K and 392–400 K, respectively, both with decomposition) were above that of D-lyxose (381–385 K). Both of the D-lyxose adducts were stable on storage in a sealed container at room temperature.
2. Structural commentary
The newly formed chiral centre at C1 has the S-configuration (Fig. 2) and the for the salt is sodium (1S,2S,3S,4R)-1,2,3,4,5-pentahydroxypentane-1-sulfonate. The anion has an open-chain structure in which one of the oxygen atoms, O13, of the sulfonate residue, the S atom, the C atoms of the sugar chain and the oxygen atom, O5, of the terminal hydroxymethyl group form an essentially planar zigzag (all-trans) chain with the corresponding torsion angles lying between the absolute values of 179.80 (11) and 167.74 (14)°. The atoms O13–C4 form a plane, with C5 and O5 displaced 0.229 (3) and 0.525 (2) Å, respectively, from that mean plane. All of the hydroxyl groups form medium-strength to weak intermolecular hydrogen bonds which connect molecules in an extensive three-dimensional network (Fig. 3 and Table 1). This network is enhanced through complexation of the sodium atom which has a coordination sphere of six oxygen atoms with an approximately octahedral pattern in which three sites are occupied by oxygen atoms O1, O2, and O11 of one basic D-lyxose-sulfonate unit and the remaining three sites are occupied by oxygen atoms O12 and O13 arising from two different sulfonate groups, and O5 of another D-lyxose-sulfonate unit. The Na—O bond lengths lie in the range 2.2524 (16) to 2.5265 (16) Å. The sodium atoms are linked in planes parallel to the ab plane through coordinating sulfonate groups supported by H–O⋯Na coordination and hydrogen bonds (Fig. 4). There is no symmetry in this all the molecules lie parallel and are arranged by translation parallel to the cell axes.
A comparison of the crystal structures of the sodium and potassium bisulfite adducts of D-lyxose illustrates the different coordination requirements of the two alkali metal cations. In the potassium salt hydrate (Haines & Hughes, 2015), two distinct environments for the cation are observed, involving both hexa- and octa-coordination of oxygen atoms, with each cation lying on a twofold symmetry axis. Oxygen atoms from the water of crystallization provide two of the coordination sites for the octa-coordinate potassium ion. In contrast, the sodium salt lacks water of crystallization and possesses a much simpler having one environment only for the cation with hexa-coordination of oxygen atoms. However, in both cases the structures accommodate a nearly planar zigzag chain incorporating the sulfur atom, the five sugar carbon atoms and the oxygen of the terminal hydroxymethyl group, and both adducts crystallize with the same S-configuration at the newly formed chiral centre, despite evidence for the existence of the R-stereoisomer in solution.

On further storage, crystals (0.313 g) were deposited, m.p. 417.6–420.1 K (decomp.) and after concentration of the mother liquors, a further crop (0.204 g) was obtained, m.p. 414–420 K; [α]D21 +8.9 (12 min.)

In the 13C NMR spectrum, based on peak heights, the corresponding ratios were: 15.69 : 5.23 : 71.90 : 7.19.
HRESMS (negative ion mode, measured in H2O/MeOH, solution) gave a peak at m/z 149.0458 ([C5H9O5]−), a significant peak at 213.0075 ([C5H11O8S1 – H2O]−), and the base peak at 299.0982 ([C10H19O10]−). No significant peak was observed for ([C5H11O8S1]−) at the calculated m/z of 231.0180.

(c, 0.68 in 9:1 H2O:HOAc). 1H NMR (D2O, 400 MHz, reference Me3COH at δH 1.24): δH 5.00 (d, J1,2 = 4.6 Hz, H-1 of α-pyranose), 4.86 (d, J1,2 = 1.4 Hz, H-1 of β-pyranose); signals for the major acyclic sulfonate: δH 4.71 (d, J1,2 = 0.6 Hz, H-1), 4.19 (dd, J2,3 = 9.5 Hz, H-2), 3.99 (td, J3,4 = 6.4, J4,5b = 6.4, J4,5a =1.2 Hz, H-4), 3.63 (dd, J5a,5b = - 9.4 Hz, H-5a); for the minor acyclic sulfonate: δH 4.63 (d, J1,2 = 5.4 Hz, H-1); ratio of major to minor sulfonate = 9.2:1. 13C NMR (D2O, 100 MHz, reference Me3COH at δC 30.29): δC 94.81 (C1, β-pyranose), 94.68 (C1, α-pyranose); signals for the major acyclic sulfonate: δC 82.17 (C1), 70.43, 69.85, 69.32 (C2, C3, C4), 63.78 (C5); the minor acyclic sulfonate showed a peak at δC 84.21 (C1).
Integration of the various signals for H-1 in the 1H NMR spectrum indicated the species α-pyranose, β-pyranose, major acyclic sulfonate and minor acyclic sulfonate were present in the % ratios of 11.62:5.47:74.78:8.14. In the 13C NMR spectrum, based on peak heights, the corresponding ratios were: 15.69:5.23:71.90:7.19.
HRESMS (negative ion mode, measured in H2O/MeOH, solution) gave a peak at m/z 149.0458 ([C5H9O5]-), a significant peak at 213.0075 ([C5H11O8S1 – H2O]-), and the base peak at 299.0982 ([C10H19O10]-). No significant peak was observed for ([C5H11O8S1]-) at the calculated m/z of 231.0180.

details are summarized in Table 2. Hydrogen atoms were located in difference maps and were refined freely with isotropic thermal parameters, except for H1 and H3 for which the Uiso values were set at the positive value of 0.010 (rather than refining to a very low or negative value).Data collection: CrysAlis PRO (Agilent, 2014); cell

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