The crystal structure of β-Na0.33V2O5 (C2/m, Z = 6) has been studied on compression to 19 GPa at room temperature using synchrotron single-crystal diffraction in a diamond anvil cell. The vanadate bronze undergoes a phase transition to a non-superconducting phase at about 12 GPa due to changes of...

The crystal structure of β-Na0.33V2O5 (C2/m, Z = 6) has been studied on compression to 19 GPa at room temperature using synchrotron single-crystal diffraction in a diamond anvil cell. The vanadate bronze undergoes a phase transition to a non-superconducting phase at about 12 GPa due to changes of polyhedral connectivities in the vanadate framework and due to ordering of the Na+ cations. This novel structure (Cm, Z = 6) is interpreted as an intermediate stage in the sequence of pressure-induced transformations in the β-A 0.33V2O5 bronzes (A: Li, Na) at room temperature. This study reveals the close relation between the loss of the two-leg ladder V–V system and non-superconducting state of the β-A 0.33V2O5 materials. |
