Sr₃Al₁₀SiO₂₀ from single-crystal data

A. Rief and F. Kubel

Abstract: Single crystals of tristrontium decaaluminum silicon icosaoxide were synthesized by local flux growth with H₃BO₃ as mineralizer. Lattice parameters and refinement data indicate no significant incorporation of B in the structure. Pairs of AlO₆ octahedra are located between layers of edge-linked Al/Si-O₄ tetrahedra. The Sr1 (2/m symmetry) and Sr2 (mirror plane) sites are orientated in layers perpendicular to the layers of Al/Si-O polyhedra.
