Abstract
The data for superconducting PrBa2Cu3O7 and Pr2-zCezSr2Cu2NbO10 indicate th at the superconductivity of these compounds is normally unaffected by rare- earth-site Pr but is quenched by a Pr-Ba or Pr-Sr defect on the other side of an adjacent cuprate-plane. Hence the primary superconducting condensate must reside not in the cuprate planes, but in the charge-reservoir regions containing hypocharged oxygen, namely in the BaO layers or the CuO chain la yers of PrBa2Cu3O7, and in the SrO layers of Pr2-zCezSr2Cu2NbO10.
