The interaction of the components of the Ce-Ru-Ge system at 600 degrees C w
as investigated over the whole concentration range by X-ray powder and X-ra
y microprobe analysis. The formation of the previously reported phases, CeR
u2Ge2 and Ce2Ru3Ge5, was confirmed and five new ternary compounds were obse
rved. The crystal structures of CeRuGe3 and CeRuGe were determined. (C) 199
