Abstract
Crystals of DyTa7O19 were obtained by a chemical transport reaction us ing NH4Cl as the transport agent, The structure was refined in space g roup P (6) over bar c2 and is built up from double layers of Ta2 polyh edra, which may be described as edge-shared pentagonal bipyramids, alt ernating with layers of [Ta3Dy3O30] rings.
