Raman scattering measurements and lattice-dynamics calculations have beenperformed on magnesium tungstate under high pressure up to 41 GPa. Experimentshave been carried out under a selection of different pressure-media. Theinfluence of non-hydrostaticity on the structural properties of MgWO4 andisomorphic compounds is examined. Under quasi-hydrostatic conditions a phasetransition has been found at 26 GPa in MgWO4. The high-pressure phase has beententatively assigned to a triclinic structure similar to that of CuWO4. We alsoreport and discuss the Raman symmetries, frequencies, and pressure coefficientsin the low- and high-pressure phases. In addition, the Raman frequencies fordifferent wolframites are compared and the variation of the mode frequency withthe reduced mass across the family is investigated. Finally, the accuracy oftheoretical calculations is systematically discussed for MgWO4, MnWO4, FeWO4,CoWO4, NiWO4, ZnWO4, and CdWO4.
