摘要：

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, Z = 4, a = 4.00544(7), b = 10.5426(2), c = 14.1369(3) angstrom, R(I) = 5.92, R(p) = 10.69, R(wp) = 9.54, R(exp) = 4.39%). The location of the atoms in Er3Ge, is similar to that in the W3CoB3 Structure, with the Ge atoms substituting for Co and B. For the other R3Ge4 compounds (R=Ho, Tm and Lu) the lattice parameters are given.
