With the exception of the terminal hydroxy group [N—C—C—O = 53.8 (5)°], the cation of the title salt hydrate, C5H14NO+·C14H9O4S2−.H2O, is a straight chain. A twisted conformation is found for the anion [C—S—S—C = −87.44 (16)°]. In the crystal, the anions self-assemble into a helical supramolecular chain via charge-assisted O—H⋯Oc hydrogen bonds. These chains are connected into a three-dimensional network via N—H⋯Oc, N—H⋯Ow, Oh—H⋯Ocb, and Ow—H⋯Oc hydrogen-bonding interactions (c = carboxylate, w = water, h = hydroxy and cb = carbonyl).

The title salt (I) was obtained by dissolving 2-[(2-carboxyphenyl)disulfanyl]benzoic acid (0.100 g, Fluka) in ethanol (20 ml) to which was added the amine in 1:1, 1:2 and 1:3 stoichiometric ratios in three separate experiments. Regardless of the stoichiometry, only crystals of (I) were harvested as proved by multiple
determinations, m.pt. 429–431 KThe H-atoms located from difference maps but placed in their idealised positions (O–H = 0.84 Å, N–H = 0.90 Å, and C–H 0.93-0.97 Å) and were included in the
in the riding model approximation with Uiso(H) set to 1.2-1.5Ueq(carrier atom). The maximum and minimum residual electron density peaks of 1.11 and 0.43 e Å-3, respectively, were located 0.91 Å and 0.60 Å from the H15b and O1w atoms, respectively.Data collection: CrystalClear (Rigaku/MSC, 2005); 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. |
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. |

The title salt hydrate, (I), was obtained during crystallisation experiments involving various N-containing species with the dicarboxylic acid, 2-[(2-carboxyphenyl)disulfanyl]benzoic acid (Broker & Tiekink, 2007; Broker et al., 2008). The asymmetric unit of (I) comprises an aminium cation, Fig. 1, a uninegative 2,2'-dithio(benzoic acid)benzoate anion, Fig. 2, and a solvent water molecule of crystallisation.
The cation is linear with the exception of the terminal hydroxyl group which is twisted out of the chain as seen in the O5–C15–C16–N1 torsion angle of 53.8 (5) °. Confirmation of protonation of the amine-N1 atom during crystallisation is seen in the pattern of hydrogen bonding interactions, see below. A search of the CSD (Bruno et al., 2002) suggests that this is the first structural characterisation reported for the 2-hydroxyethyl(propyl)aminium cation. The 2,2'-dithio(benzoic acid)benzoate molecule is twisted [C3–S1–S2–C10 = -87.44 (16) °] in accord with expectation with the conformation stabilised by intramolecular S···O interactions of 2.633 (3) Å for S2···O3 and 2.647 (3) Å for S3···O4 (Broker & Tiekink (2007). Confirmation that the C8—O1, O2 residue is in the acid form is found in the disparity of the C1–O1 and C1–O2 bond distances, i.e. 1.212 (4) and 1.316 (4) Å, respectively, compared with the equivalence of the C8–O3 and C8–O4 bond distances of 1.266 (4) and 1.247 (4) Å, respectively. The O1-carboxylic acid group is co-planar with the benzene ring to which it is connected with the C3–C2–C1–O1 and torsion angle being -2.9 (5) Å, but the O3-carboxylate group is not: the O3–C8–C9–C10 torsion angle being -21.0 (5) °.
The most distinctive feature of the crystal packing is supramolecular chain formed via self-association between 2,2'-dithio(benzoic acid)benzoate anions, as normally seen for such species (Broker & Tiekink, 2007), Fig. 2 and Table 1. The chain has a helical topology being generated by 21-screw symmetry along the b axis of the monoclinic unit cell. The next most prominent O–H···O interaction involves the O5-hydroxyl group and the carbonyl-O1 atom. The remaining carboxylate-O4 associates with the water molecule of crystallization. The water molecule also forms a hydrogen bond with a neighbouring carboxylate-O3 atom and with a centrosymmetrically related water molecule to form a 12-membered {···OCO···HOH}2 synthon. The aminium-H2n atom forms a donor interaction to a O1w-water molecule so that the latter participates in three hydrogen bonds. The second ammonium-H1n atom forms a N—H···O hydrogen bond with the carboxylate-O4 atom which is also connected to the O1w-water molecule and therefore closes a 12-membered centrosymmetric {···O···HNH···OH}2 synthon. In this way the components of the crystal structure are linked into a 3-D network, Table 1.
