| Abstract: | Telluride Halides of Copper with High Ionic Partial Conductivity. The Crystal Structure of CuTeI Copper telluride iodide, CuTeI, which has a high copper(I) ionic partial conductivity, could be obtained as crystals and the structure determined (359 hkl, R = 0.031). The space group is I41/amd with the lattice constants a = 17.170, c = 4.876 Å, and Z = 16. Characteristic for the structure are the helicoidal arrangements of the tellurium atoms, symmetry related by fourfold screwaxes (41) and the statistical population of the Cu sites. The latter is a hint for a copper ionic conductivity. |
