Single phase of CeCuS2 has been prepared by the mixture of CeO2 and Cu2S at 1000 ° C in CS2/Ar atmosphere. All X-ray diffraction peaks of CeCuS2 are indexed on the basis of the monoclinic system (space group: P21c) the same as LaCuS 2 and NdCuS2. The lattice parameters obtained by Rietveld analysis are a=0.6573(1) nm, b=0.7256(1) nm, c=0.6875(1) nm, and β=98.566(1)°. © 2005 Elsevier B.V. All rights reserved.
