摘要：
The crystal structure of the rare earth (RE) compound CeFeGe3 has been studied by X-ray powder diffraction and refined by the Rietveld profile fitting method. The compound has the tetragonal BaNiSn3-type structure, space group I4mm (No. 107) a=4.3294(1) Angstrom, c=9.9444(3) Angstrom, V = 186.39 Angstrom(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.
