-5,7-dihydroxy-4-oxo-2-phenyl-4H-chromene-8-sulfonato)potassium(I)]Abstract: In the polymeric title compound, [K(C15H9O7S)]n, the potassium cation is five-coordinated by four sulfonate O atoms and one carbonyl O atom. Two intramolecular O-H
O hydrogen bonds stabilize the conformation of the anion. The polymeric three-dimensional supramolecular architecture is formed via coordination interactions and ![[pi]](/logos/entities/pi_rmgif.gif)
- stacking interactions involving centrosymmetrically related pyrone rings, with a centroid-centroid separation of 3.513 (2) Å.
