6+x and several other superconducting 1-2-3 compounds. These findings are explained by the tendency of Pr
III to form Pr
IV, which can be responsible for the absence of superconductivity, and charge transfer between the Cu(2)-O sheets and Cu(1)-O chains. It is also concluded that at high oxygen stoichiometries the Cu(1)-O chains have metallic character for both compounds.
