Abstract

A new perovskite-type cuprate PrCuO₃ has been synthesized by high-pressure oxygen annealing. Synchrotron X-ray powder diffraction and absorption spectroscopy revealed that PrCuO₃ crystallizes in the GdFeO₃-type structure with cooperative Jahn-Teller distortion, forming one-dimensional chains of corner-shared CuO₄ plaquettes with nearly divalent Cu ions.
