Abstract
The single phase of Y1-xPrxBaSrCu3O7-delta has been investigated by po wder X-ray diffraction and temperature dependence of the resistivity. It is found that the system undergoes an orthorhombic-to-tetragonal tr ansition at x=0.5. Superconductivity still survives until x=0.7. These results have been compared with those of the Y1-xPrxBa2CU3O7-delta sy stem, which was discussed in terms of the Pr-O covalent bonding effect .
