摘要：

The ordered perovskite Sr2YTaO6, distrontium yttrium tantalum hexaoxide, has been reported as showing an unusual triclinic structure, at odds with the results from a recent group-theoretical analysis. A new investigation establishes that Sr2YTaO6 and the isostructural Sr2YNbO6, distrontium yttrium niobium hexaoxide, in fact both adopt the commonly occurring monoclinic structure, with the space-group symmetry P2(1)/n.
