Abstract The crystal structure of the superconducting compounds RBa2Cu3O9−δ where R is one of the rare earth metals Ho, Eu or Y, has been studied at room-temperature at pressures up to 60 GPa by synchrotron X-ray powder diffraction in a diamond anvil cell using the energy dispersive method At increasing pressure the compounds show semilar behavior with a bulk modulus in the range 140–176 GPa and a phase transition from an orthorhombic to a tetragonal structure at around 20 GPa. The transition is without a volume change and shows no hysteresis.
