Crystal structure of the Ca3TaGa3Si2O14 compound

Synthesis and Characterization of the New Strontium Borogermanate Sr3–x/2B2–xGe4+xO14 (x = 0.32)

“…This transformation can be observed e.g. in the structure of Ca 3 TaGa 3 Si 2 O 14 . The strontium cation in the center of the polyhedron is displaced along the a axis from the short O2–O2 edge shared with the germanium octahedron (position 1 a ) toward the longer O1–O1 edge (Figure b).…”

“…in the structure of Ca 3 TaGa 3 Si 2 O 14 . 33 The strontium cation in the center of the polyhedron is displaced along the a axis from the short O2−O2 edge shared with the germanium octahedron (position 1a) toward the longer O1−O1 edge (Figure 2b). The observed bond angels and lengths within the structure are in good agreement to those of other borogermanates and the isotypic phase Sr 3 Ga 2 Ge 4 O 14 .…”

“…Therefore, BTGS should have an ordered 25) The average TaO, GaO, and SiO distances are 1.981, 1.849, and 1.633 ¡, respectively. These values are the same as those in Ca 3 TaGa 3 Si 2 O 14 (CTGS) 31) and STGS. 22) This result suggests that ionic size in the A site affects physical properties.…”
