4-(4-Hydroxy-3,5-dimethylphenylazo)benzenesulfonic Acid

Acta Crystallographica Section C Crystal Structure Communications, 1995
In the solid state, the title compound, C 14 H 14 N 2 O 4 S.-H 2 O, exists as two forms: cubes (I) and needles (II). Both kinds of crystal are monohydrates. The dye molecules have the same geometry and are bonded by O-H...O intermolecular hydrogen bonds in both forms: an N + -H...O - intermolecular hydrogen bond in (II) and an N + -H...(O) 2 ...

Do enantiomers of benzenesulfonic acid exist? Electron diffraction and quantum chemical study of molecular structure of benzenesulfonic acid

Journal of Molecular Structure, 2012
Abstract Molecular structure of benzenesulfonic acid was studied by gas-phase electron diffraction and quantum chemical (B3LYP/cc-pVTZ, МР2/cc-pVDZ, МР2/cc-pVTZ) methods. On the base of mass spectrometric analysis it was found that saturated vapor at Т = 396(9) K is represented by only molecular species, monomeric benzenesulfonic acid.
