Beschreibungen/Notizen

• Group‐theoretical methods are used to enumerate the structures of ordered double perovskites, A2BB′X6, in which the ordering of cations B and B′ into alternate octahedra is considered in combination with the ubiquitous BX6 (or B′X6) octahedral tilting. The cation ordering on the B‐cation site is described by the irreducible representation of the space group of the cubic aristotype, while the octahedral tilting is mediated by irreducible representations and . There are 12 different structures identified, and the corresponding group–subgroup relationships are displayed. Known structures are briefly reviewed.
