title: Potassium 4-azidobenzene-sulfonate.
abstract: In, K(+)·SO3-p-C6H4-N3 (-), the conformation angle of the azido group with respect to the benzene ring is 19.1 (3)°, so that the anion is chiral within the crystal structure. In addition, the crystal structure is also chiral (Sohncke space group). The potassium ion is coordinated by three closer O atoms from three different sulfonyl groups [K⋯O 2.6486 (17) to 2.7787 (17) Å], three more distant O atoms [K⋯O 2.959 (2) to 3.206 (2) Å] and three N atoms at 3.073 (2) to 3.268 (2) Å. The anions are packed into layers perpendicular to b, only O and N atoms being at the surface of the layers. The K(+) ions are located between the layers.
