A Site

The new layered title compound, barium di-μ-hydroxido-di-μ-vanadato-tricobaltate(II), was prepared under low-temperature hydrothermal conditions. Its crystal structure comprises Co2+and O2−ions in the Kagomé geometry. The octahedral Co3O6(OH)2Kagomé layers, made up of edge-shared CoO4(OH)2octahedra with Co on a site of 2/msymmetry, alternate along thecaxis with barium vanadate heteropolyhedral layers, in which Ba is on a site of \overline{3}msymmetry and V is on a site of 3msymmetry. All three O atoms and the H atom also occupy special positions: two O atoms and the H atom are on sites with 3msymmetry and one O atom is on a site withmsymmetry. Ba[Co3(VO4)2(OH)2] represents the first compound from the four-component BaO–CoO–V2O5–H2O system and its structure is topologically related to the minerals vesignieite, Ba[Cu3(VO4)2(OH)2], and bayldonite, Pb[Cu3(AsO4)2(OH)2].

The Stability

The high-pressure and low-temperature behaviour of the GeSe x Te1−x system (x = 0, 0.2, 0.5, 0.75, 1) was studied using a combination of powder diffraction measurements and first-principles calculations. Compounds in the stability field of the GeTe structure type (x = 0, 0.2, 0.5) follow the high-pressure transition pathway: GeTe-I (R3m) → GeTe-II (f.c.c.) → GeTe-III (Pnma). The newly determined GeTe-III structure is isostructural to β-GeSe, a high-pressure and high-temperature polymorph of GeSe. Pressure-dependent formation enthalpies and stability regimes of the GeSe x Te1−x polymorphs were studied by DFT calculations. Hexagonal Ge4Se3Te is stable up to at least 25 GPa. Significant differences in the high-pressure and low-temperature behaviour of the GeTe-type structures and the hexagonal phase are highlighted. The role of Ge...Ge interactions is elucidated using the crystal orbital Hamilton population method. Finally, a sketch of the high-pressure phase diagram of the system is provided.
