Double Double to Double Perovskite Transformations in Quaternary Manganese Oxides [PDF]
Angewandte Chemie International Edition, 2021 AbstractControl of cation ordering in ABX3 perovskites is important to structural, physical and chemical properties. Here we show that thermal transformations of AA′BB′O6 double double perovskites, where both A and B sites have 1:1 cation order, to (A0.5A′0.5)2BB′O6 double perovskites with fully disordered A/A′ cations can be achieved under pressure in

Double and double double perovskites in the RMnMnTaO6 series [PDF]
Journal of Solid State Chemistry, 2022 A new family of perovskites RMnMnTaO6 has been synthesised at high pressure for representative R = La, Nd, Sm, Eu, Gd, Y and Lu that span the whole rare earth series. The structure type changes from tetragonal P42/n double double perovskite (DDPv) type with columnar R3+/Mn2+ cation order (R = La, Nd, Sm) to monoclinic P21/n double perovskite (DPv) (
