Abstract: | The crystal structure of binary germanides R3Ge4 (R Er, Ho, Tm, Lu) has been determined by means of powder X-ray diffraction. For Er3Ge4 a full-structure determination has been performed using the Rietveld method (306 reflections, space group Cmcm, ). The location of the atoms in Er3Ge4 is similar to that in the W3CoB3 structure, with the Ge atoms substituting for Co and B. For the other R3Ge4 compounds (RHo, Tm and Lu) the lattice parameters are given. |
