Аннотация: A number of new intermetallic compounds of variable composition, RRuxGa1 – x(R = Er, Tm, Lu)and R2Ru1 – xIn1 + x (R = Dy, Ho, Er, Tm, Lu), whose structures belong to known structure types, have beenidentified in a systematic study of R–Ru–Ga and R–Ru–In systems in their rare-earth-rich region. The Gaand Ru atoms in the RRuxGa1 – x intermetallic phases with the CsCl structure (Pm m) occupy the Cs site atrandom. The R2Ru1 – xIn1 + x compounds have the Pt2ZnCd structure (P4/mmm), derived from the CsClstructure via doubling of its c cell parameter, and the Ru and In atoms in these compounds occupy the Cs sitein an ordered manner. All of the synthesized compounds have a homogeneity range, whose extent is highlydependent on the nature of the RE element. In the R–Ru–Ga (R = Er, Tm) systems, we have identified newcompounds with the general formula RRuyGa1 – y and the MoB structure (I41/amd), which is in turn derivedfrom the CrB structure type (Cmcm). The homogeneity range of the RRuyGa1 – y intermetallic phases withthe MoB structure is 0.05 < y < 0.20.
