TL;DR: In this article, the double layers of Ta2 polyhedra that may be described as edge-shared penta-gonal bipyramids alternating with the layers of [Ta3Dy3O30] rings were refined in space group P\overline{6}c2.
Abstract: Crystals of the compound DyTa7O19 could be obtained by chemical transport reaction using NH4Cl as the transport agent. The structure was refined in space group P\overline{6}c2. The structure is built up from the double layers of Ta2 polyhedra that may be described as edge-shared pentagonal bipyramids alternating with the layers of [Ta3Dy3O30] rings.

TL;DR: The title compound of as mentioned in this paper is isostructural with La2Ta3S2O8, and the distances in the octahedral layers are 3.314(4), 3.775(1) and 4.236(4)A. The structure comprises alternate layers of Sm tricapped trigonal prisms and Ta octahedra.
Abstract: The title compound is isostructural with La2Ta3S2O8. The Sm atoms are in tricapped trigonal prismatic sites enclosed by two S and seven O atoms. The Ta atoms are octahedrally coordinated, one to six O atoms and the other to two trans-O and four S atoms. The structure comprises alternate layers of Sm tricapped trigonal prisms and Ta octahedra. The Ta(1)...Ta(1) distances in the octahedral layers are 3.314(4), 3.775(1) and 4.236(4)A.
