High-pressure structures of [alpha]- and [bold delta]-ZrMo2O8

A. M. Krogh Andersen and S. Carlson

Abstract: In situ high-pressure synchrotron X-ray powder diffraction studies of trigonal [alpha]-ZrMo2O8, zirconium molybdate, have been performed from ambient conditions to 1.9  GPa, over the [alpha]-[bold delta] phase transition at 1.06-1.11  GPa. The monoclinic structure of [bold delta]-ZrMo2O8, stable between 1.1 and 2.5  GPa  at 298  K, has been solved by direct methods and refined using the Rietveld method. Significant distortions of the ZrO6 and MoO4 polyhedral elements are observed for [bold delta]-ZrMo2O8, as compared to the ambient conditions of the [alpha]-phase, while the packing of anions becomes more symmetric at high pressure.
