Source of material
The compound was obtained commercially (Merck). Crystals suitable for the diffraction study were taken directly from the provided product.
Experimental details
Carbon-bound H atoms were placed in calculated positions (C–H 0.95 Å for aromatic carbon atoms) and were included in the refinement in the riding model approximation, with U(H) set to 1.2Ueq(C).
The H atoms of the methyl groups were allowed to rotate with a fixed angle around the C–C bond to best fit the experimental electron density (HFIX 137 in the SHELX program suite [3]), with U(H) set to 1.5Ueq(C).
The H atoms of the water molecules as well as the bridging H atom of the H5O2+ cation were located on a difference Fourier map and refined freely. The position of the aforementioned bridging H atom was refined approximately midway between the two water O atoms, suggesting H atom disorder.
The Flack x = 0.070(16) parameter was determined using 1088 quotients [7].
Comment
Several simple and fundamental derivatives of benzene are powerful and versatile reagents in industry and academic research alike and have entered the preparative chemist’s toolbox decades ago. One notable example for the latter statement are benzenesulphonic acid and its alkylated derivatives such as para-toluenesulphonic acid which are readily available upon reacting the parent hydrocarbon with concentrated sulphuric acid [8] and find widespread use as reagents of intermediate strength whose solubility in organic solvents is of crucial interest. In continuation of our interest in structural aspects of acidic derivatives of benzene [9], [10], [11], [12], [13], [14] the molecular and crystal structure of the title compound was determined. Structural information about para-toluenesulphonic acid [15] as well as several compounds featuring the title compound bonding to main group elements such as tin [16], [, 17] is available in the literature.
The structure solution shows the presence of the 2,5-dimethylsulphonate scaffold as well as two molecules of water. A closer inspection of the hydrogen atom positions reveals the title compound to exist as a hydrated oxonium salt featuring the H5O2+ cation in the solid state. S–O bond lengths measure 1.4545(15)–1.4724(15) Å, which is in good agreement with values found for other deprotonated benzenesulphonic acid derivatives whose metrical parameters have been deposited with the Cambridge Structural Database [18].
The crystal structure is dominated by classical hydrogen bonds of the O–H⋯O type involving all oxygen atoms of the sulphonate anion as acceptor. In terms of graph-set analysis [19], [, 20], the descriptor for these hydrogen bonds is DDDDD at the unitary level. In total, the entities of the title compound are connected to double layers perpendicular to the crystallographic c axis. π-Stacking does not play an important role in the crystal structure as the shortest distance between two centers of gravity was measured at 5.1042(13) Å.
