摘要： A new structural phase of MgV2O6 was obtained by a high-pressure, high-temperature (HPHT) synthesis method. The new phase was investigated by Rietveld analysis of X-ray powder diffraction data, showing space group Pbcn (No. 60) symmetry and a=13.6113(6) Å (1 Å=0.1 nm), b=5.5809(1) Å, c=4.8566(3) Å, V=368.93(2) Å3 (Z=4). High pressure behavior was studied by Raman spectroscopy at room temperature. Under 22.5 GPa, there was no sign of a structural phase transition in the spectra, demonstrating stability of the HPHT phase up to the highest pressure.
