Abstract

Crystal structure analyses of new compounds, Cu6O8Cu2X (X = Cl, NO3), have been carried out using the X-ray powder pattern fitting method (Rietveld method) together with thermal analyses. Although these compounds have a face-centered cubic structure analogous to that of Cu6OgInCl previously reported with a space group of Fm3m, the Cu2 (24e site) ions have a quite different configuration from that of the corresponding In ion. From the results of the above- mentioned analyses together with chemical analyses, the compositions of these samples were obtained as Cu5.7 O8Cu1.9Cl0.69(NO3)0.31 and CCu5.7 O8Cu1.9Cl0.69NO3respectively. The unit cell parameters are a = 9.376(1) Å for the former and 9.481(1) Å for the latter. These compounds decompose to CuO at 400°C and 350°C, respectively.
