- Аннотация: New ternary intermetallic compound Sm3RuSn6 have been synthetized by arc melting under argon from the pure elements. The structure was established for the isothermal section at 620 °C by the X-ray powder diffraction and EMPA methods. The crystal structure for new ternary phase were assigned to known structure type based on XPD Rietveld refinements – Y3CoSn6, space group – Cmcm (№60). The unit cell parameters are a=4.4139(3) Ǻ, b=16.6102(8) Ǻ, c=13.2827(7) Ǻ, V=1332.1(4) Ǻ3. The structure is similar with the investigated earlier compound of same compositon with cerium – Ce3RuSn6 and characterized by two independent crystallographic position of samarium – 8f and 4c. Interatomic contacts between the rare earth and transition metals are not shortened: d(Sm1-Ru1) = 3.3418(3) Å, d(Sm2-Ru1) = 3.6233(4) Å.
