- Аннотация: In the R–Ru–In (R—rare earth element) systems in the area with a high content of rare-earth elements (>60 at %), a number of isostructural compounds R26(RuxIn1 – x)17 (R = Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Lu) were found, which crystallize in a tetragonal cell (P4/mbm) with the Sm26(Co0.65Ga0.35)17 structure type, as well as Pr21Ru8.2In5 compounds in a tetragonal cell (I4/mcm) with the Y3Rh2 structure type and Gd6Ru2In in a rhombic cell (Immm) with the Ho6Co2Ga structure type. The samples were prepared by arc-melting the stoichiometric quantities of elementary components. The structures were determined by single-crystal X-ray diffraction and refined by the Rietveld method using powder patterns. Compounds R26(RuxIn1–x)17 (R = Dy, Ho, Er, Tm, Lu) exist in the homogeneity range 0.28 < x < 0.47. All crystal structures of the obtaining compounds are based on a frame from atoms of rare earth elements, inside which are smaller in size atoms of ruthenium and indium. A general fragment of all the considered structures are columns of various lengths from InR8 tetragonal prisms and RuR8 tetragonal antiprisms conjugated by mutual bases. The new compounds have a congruent melting pattern.
