ChemInform Abstract: Twinned Caesium Cerium(IV) Pentafluoride.

Abstract

Single crystals of CsCeF3 are prepared hydrothermally from a 1:5 molar mixture of CeF4 and CsF (autoclave, 250 °C, 1 d).

Crystal structures and stability of LiCeF5and LiThF5at high pressures

“…Our work is performed not only at atmospheric conditions but also at high pressures using single-crystal x-ray diffraction in diamond anvil cells on laboratory diffractometers and at synchrotron facilities. The results of our studies so far [2][3][4][5] indicate that most of the materials with low-dimensional structures built of chains or layers of face-or edgesharing Th-F polyhedra are structurally stable at least to about 10 GPa at room temperature. This observation suggests that moderate high pressure has hardly any effect on the coordination polyhedra around the Th atoms and the topology of the structure of complex thorium fluorides.…”
