X-ray powder diffraction data and structure refinement of CeFeGe3

The crystal structure of the rare earth (RE) compound CeFeGe 3 has been studied by X-ray powder diffraction and refined by the Rietveld profile fitting method. The compound has the tetragonal BaNiSn 3 -type structure, space group I 4 mm (No. 107) a =4.3294(1) A, c =9.9444(3) A, V =186.39 A 3 , Z =2, and Dx =7.372 g · cm −3 . The figure of merit F N for the powder data is F 30 =184.3(0.0037,44). The structure refinement was performed with 106 reflections and led to R p =13.2% and R wp =18.2%. Powder data are given.
