Abstract

A new compound CurNasOt has been formed with composition given roughly by r:s:t equal to 5:2:7 and nominal Cu valence roughly 2.4+. The unit cell is close to orthorhombic, with a slight monoclinic distortion. The material was fabricated by a solid state reaction between CuO and NaCuO2 at pressure exceeding 40Kbar and temperature exceeding 800°C. The product is multi-phased, containing CuO and the new material. The electrical properties of the multi-phased product are those of a narrow gap semiconductor. No superconductivity was detected down to 4.2K.
