In the crystal structure of the title hydrated salt, poly[(μ2-aqua)(μ4-1-sulfido-β-D-glucoside)potassium], [K(C6H11O5S)(H2O)]nor K+·C6H11O5S−·H2O, each thioglucoside anion coordinates to four K+cations through three of its four hydroxy groups, forming a three-dimensional polymeric structure. The negatively charged thiolate group in each anion does not form an efficient coordination bond with a K+cation, but forms intermolecular hydrogen bonds with four hydroxy groups, which appears to sustain the polymeric structure. The Cremer–Pople parameters for the thioglucoside ligand (Q= 0.575, θ = 8.233° and φ = 353.773°) indicate a slight distortion of the pyranose ring.
