Popis: We have investigated the pressure-dependent structural properties of the quasi-one-dimensional metal at room temperature by high-resolution angle-dispersive powder X-ray diffraction. According to our structural data, the crystal lattice of β-Na0.33V2O5 remains monoclinic (space group C2/m) up to 20 GPa. The smallest compressibility is found along the conducting b-axis. We observe an anomaly in the pressure dependence of the lattice parameters and the volume of the unit cell in the range 12–15 GPa, in agreement with the pressure-dependent optical properties.
