CRYSTAL STRUCTURE OF THE RNa 4 Sn 6 (R = Yb, Eu) ; КРИСТАЛІЧНА СТРУКТУРА RNa 4 Sn 6 (R = Yb, Eu)
Abstract
The crystal structure of the ternary phases YbNa 4 Sn 6 (a = 10.0532(2), c = 7.1246(1) Å) and EuNa 4 Sn 6 (a = 10.0828(3), c = 7.1671(1) Å), which belongs to the CaNa 4 Sn 6 structure type (space group P6 3 /mmc, Pearson symbol hP22) was investigated by single crystal method using single crystal diffractometer XCALIBUR (MoKa-radiation). Both structures was solved by means direct method. Atomic and thermal displacement parameters are refined by SHELX-97. The results of calculation and refinement of the crystal structure of the compounds YbNa 4 Sn 6 and EuNa 4 Sn 6 showed that it is isostructural to the structure type СаNa 4 Sn 6 , where the position of the Ca 2 (b) atoms occupy Yb and Eu. The coordination polyhedra of rare-earth metal atoms are 16-vertex polyhedra and the coordination polyhedra of tin atoms are 10-vertex polyhedra. Pentagonal- and trigonal-prismatic coordinations are typical for sodium atoms. Tin atoms form isolated hexagonal prisms [RSn 12 ] around the atoms of rare-earth metals, next layers around these prisms consist of Na 4 -tetrahedra which are connected by Na-Na bond into 3D-carcass. Key words: intermetallic compounds, synthesis, X-ray analysis, the cryst. ; Методом монокристала досліджено кристалічну структуру тернарних фаз YbNa 4 Sn 6 та EuNa 4 Sn 6 (структурний тип CaNa 4 Sn 6 , просторова група P6 3 /mmc). Атоми стануму утворюють ізольовані гексагональні призми [RSn 12 ] навколо атомів рідкісноземельних металів, наступна сфера навколо цих призм складається з Na 4 -тетраедрів, які з’єднані між собою зв’язком Na-Na у 3D-каркас. Ключові слова: інтерметалічні сполуки, синтез, рентгеноструктурний аналіз, кристалічна структура.
