The crystal structure of a potassium adduct with a substituted (phenylthio)acetic acid has been determined using X-ray diffraction, and refined to a residual R = 0.043 for 1932 observed reflections. The adduct, [(KL)(LH)]n, where LH = (4-chloro-2,5-dimethylphenylthio)acetic acid, is triclinic, space group P1̄, Z = 2, a = 7.313(2), b = 9.386(2), c = 17.371(5) Å, α = 77.53(2), β = 79.28(2), γ = 84.95(2)°. The K atom is surrounded by a distorted octahedron comprising five oxygens [KO, 2.691-2.777(3) Å] and one sulphur atom [KS, 3.349(2) Å], with oxygens also bridging in a polymer structure. There are two hydrogen atoms at special positions contributing to the one H+. The compound is an example of a type A, [(M+)2(HX2-)2] system, with one hydrogen atom being shared by two crystallographically related X groups. There are two conformationally different (HX2-) groups in the structure.
