Electrochemical and high pressure oxygenation experiments are described which extend the range of intercalated oxygen content beyond that accessible in 1 atm O2treatments for the triangular planar cuprate delafossites YCuO2+xand LaCuO2+xwith the intention of increasing the hole doping, and filling vacancies in the intercalated oxygen lattice to decrease electrical resistivities. Stabilization of the 2H polytype of YCuO2through 1% Ca substitution for Y and oxidation conditions for obtaining the pure orthorhombic intercalated oxygen superlattice form of YCuO2.50are also described. Temperature dependent resistivities for some of the superoxygenated compositions are reported; metallic behavior was not observed.
