Isolation of the simplest hydrated acid.

ABSTRACT: Dissociation of an acid molecule in aqueous media is one of the most fundamental solvation processes but its details remain poorly understood at the distinct molecular level. Conducting high-pressure treatments of an open-cage fullerene C₇₀ derivative with hydrogen fluoride (HF) in the presence of H₂O, we achieved an unprecedented encapsulation of H₂O·HF and H₂O. Restoration of the opening yielded the endohedral C₇₀s, that is, (H₂O·HF)@C₇₀, H₂O@C₇₀, and HF@C₇₀ in macroscopic scales. Putting an H₂O·HF complex into the fullerene cage was a crucial step, and it would proceed by the synergistic effects of "pushing from outside" and "pulling from inside." The structure of the
