Descripción
Sumario:In the polymeric title compound, [K(C(15)H(9)O(7)S)](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 π–π stacking inter­actions involving centrosymmetrically related pyrone rings, with a centroid–centroid separation of 3.513 (2) Å.
