摘要：

The crystal structure of the compound CeRh2Si was studied by X-ray single crystal diffraction methods and refined to R-F = 0.038: space group Cmcm, a = 4.0413(9) Angstrom, b = 17.730(3) Angstrom, c = 4.0675(9) Angstrom, V = 291.45(10) Angstrom(3), Z = 4. The structure belongs to a structure type that can be considered as a site exchange variant of the known CeNiSi2 structure type (CeSiRh2) with slightly different axial ratios. (C) 2003 Elsevier B.V.
