%X The reaction of 4-hydroxypyridine and oleum produces 4-hydroxypyridinium-3-sulfonate, C5H5NO4S, which shows delocalized bonds in the six-membered ring. In the crystal, adjacent zwitterions are linked by N¡ªH...O and O¡ªH...O hydrogen bonds into a layer motif. The crystal studied was a racemic twin.
