Conventional view of the cubic aristotype (space group Fmm) double perovskite structure showing corner-sharing MX6 and M′X6 octahedra with the A cations residing in the cavities formed by the octahedral network. Legend: [MX6]: white octahedral/sphere; [M′X6]: grey octahedral/sphere; A: cross-hatched spheres; X: filled spheres. |
