Potassium 4-chloro-benzene-sulfonate

The structure of the title compound (K4CBS), poly[4-4-chloro-benzene- sulfonato-potassium(I)], [K(C6H4ClO3S)] n , resembles that of silver 4-chloro-benzene-sulfonate with somewhat different geometric parameters. The supra-molecular structure is constructed by Cl atoms bridging the K⁺ ions. Each K⁺ ion is hepta-coordinated by two Cl ligands and four sulfonate groups, one of them in a monodentate and three in a bidentate fashion. Thus, each sulfonate group coordinates four K⁺ ions.
