/ˈˌpɑliˌθaɪˈɑnɪk/

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: poly- comb. form, -thionic comb. form.

Etymology: < poly- comb. form + -thionic comb. form, after German Polythionsäure polythionic acid (1848 or earlier).

Chemistry.

polythionic acid n. any of a series of unstable acids containing a short chain of sulphur atoms, and having the general formula H₂S_nO₆, where n is 2, 3, 4, or more. Cf. dithionic adj., trithionic adj., tetrathionic adj., pentathionic adj.
