Na 2 MoO 2− δ F 4+ δ ( δ ∼ 0.08) displays a unique variant of the perovskite structure, with simultaneous (Na,vacancy) ordering on the A-site, (Na,Mo) ordering on the B-site, (O,F) ordering on the anion site and an unusual NaNbO 3 -like octahedral tilt system. Na 2 MoO 2− δ F 4+ δ represents the fir...

Summary:Na 2 MoO 2− δ F 4+ δ ( δ ∼ 0.08) displays a unique variant of the perovskite structure, with simultaneous (Na,vacancy) ordering on the A-site, (Na,Mo) ordering on the B-site, (O,F) ordering on the anion site and an unusual NaNbO 3 -like octahedral tilt system. Na 2 MoO 2− δ F 4+ δ represents the first example of a perovskite exhibiting simultaneous A-site, B-site and anion site order, together with a complex tilt system.
