The crystal structures of RCuPb (R=Y, Tb, Tm and Lu) compounds were investi
gated by X-ray powder diffraction. The crystal structure of DyCuPb was rein
vestigated by thr X-ray single crystal method and RCuPb (R=Sm, Gd, Dy, Ho,
Er) by X-ray powder diffraction. The compounds crystallize in the LiGaGe st
ructure type (space group P6(3)mc, Pearson code hP6). (C) 2001 Elsevier Sci
