Abstract
Possible mechanisms for the oxygen intercalation in the ternary mixed-Cu-valence YBa2Cu3O6.5+x oxide are considered, which account for the observed cell symmetry transformation driven by the oxygen concentration. These mechanisms are consistent with the formation of both single-and double-cell superstructures of ordered oxygen vacancies that have been encountered in crystallographic investigations of the high-Tc superconductor YBa2Cu3O≈7.
