R. Patschke et al., KCUCETE4 - A NEW INTERGROWTH RARE-EARTH TELLURIDE WITH AN INCOMMENSURATE SUPERSTRUCTURE ASSOCIATED WITH A DISTORTED SQUARE NET OF TELLURIUM, Chemistry of materials, 10(3), 1998, pp. 695
The quaternary compound KCuCeTe4 has an ordered intergrowth structure
made of KCuTe and CeTe3 layers. The CeTe3 layers have square nets of t
ellurium atoms which are structurally distorted to give rise to an inc
ommensurate superstructure.
