Notizen: Darstellung und Kristalldaten der isomorphen Kupferthio(seleno)phosphate Cu7PS6 und Cu7PSee / Preparation and Crystal Data of the Isomorphous Copperthio(seleno)phosphates Cu7PS6 and Cu7PSe6

Abstract

The title compounds were prepared by annealing the elements in stoichiometric proportions at 720 °C as well as by thermal decomposition of Cu3PS4 or Cu3PSe4. They crystallize in the space group P213 with lattice parameters a = 9.671(1) and 10.116(1) Å resp.; X-ray powder diffraction data are listed.
