Two crystalline associates formed in the super‐acid system HFSbF 5 have been isolated and characterized as H 3 F ⊕ 2 Sb 2 F 11 ⊖1 and H 2 F ⊕ Sb 2 F 11 ⊖ . These constitute the first crystal structure determinations on fluoronium salts. The H 3 F 2 ⊕ion of 1 contains a very strong hydrogen bridge between the two fluorine atoms and has trans conformation.
