abstract = {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.},
