Abstract
The title compound, Na+·C7H7O2S−·4H2O, is the hydrate of the sodium salt of para-toluenesulfinic acid. The molecular geometry around the sulfur atom is tetrahedral with X–S–Y angles spanning a range of 102.23 (6)–110.04 (6)°. In the crystal, the water molecules connect the sodium cations into chains along the b axis via O—H⋯O hydrogen bonds. An intermolecular O—H⋯π interaction is also observed.
