Coupled commensurate cation and charge modulation in the tunneled structure, Na0.40(2)MnO2
Na0.40(2)MnO2 belongs to a family of mixed Mn3+ and Mn4+ porous oxides that contains both octahedral and square pyramidal Mn–O units.

Below TNa, the centrosymmetric Pbam structure adopts an (ab 4c) supercell of Pnnm symmetry that accommodates a coupled commensurate modulation down the c-axis channels of both Na position and occupancy with Mn valence.

Abstract

Na0.40(2)MnO2 belongs to a family of mixed Mn3+ and Mn4+ porous oxides that contains both octahedral and square pyramidal Mn–O units. Neutron and synchrotron radiation studies identify the presence of both sodium ordering (TNa ? 310 K) and Mn charge and orbital ordering. Below TNa, the centrosymmetric Pbam structure adopts an (ab 4c) supercell of Pnnm symmetry that accommodates a coupled commensurate modulation down the c-axis channels of both Na position and occupancy with Mn valence.
