Synthèse et étude structurale de Na9Cr(MoO4)6
The title compound, nona-sodium chromium(III) hexa-kis[molybdate(VI)], Na9Cr(MoO4)6 was prepared by solid-state reactions. The basic structure units are isolated polyhedral clusters composed of a central CrO6 octa-hedron sharing vertices with six MoO4 tetrahedra to form an open framework in which the Na(+) cations are bound to the free vertices of the MoO4 tetra-hedra. The Cr(3+) cation has sit...
متن کاملSynthèse, étude et validation structurale d’un triple bis-molybdate en couches, Ag0.60Na0.40Fe(MoO4)2 lié à yavapaiite
The title compound, Ag0.60Na0.40Fe(MoO4)2 {silver sodium iron(III) bis-[molyb-date(VI)]}, was synthesized by a solid-state reaction. The structure is built up from FeO6 octa-hedra and MoO4 tetra-hedra sharing corners to form a two-dimensional framework parallel to the (001) plane. The occupationally disordered (Ag/Na)(+) cations are located in the inter-layer space. These [Fe(MoO4)2 (-)] n laye...
متن کاملSynthèse et étude structrale de lyonsite-type (Na0,4,Li0,6)(Fe,Li2)(MoO4)3
The new compound (Na0.4,Li0.6)(Fe,Li2)(MoO4)3 was synthesized by cooling from the melt. Its anionic framework is built up from two distinct MO6 octa-hedra, each containing disordered Li(+) and Fe(3+) ions in 0.6:0.4 and 0.7:0.3 ratios, and two MoO4 tetra-hedra, which link by vertex-sharing of their O atoms. These tetra-meric units are further linked by sharing edges between octa-hedra and by fo...
متن کاملElaboration, étude structurale et analyse CHARDI et BVS d’une nouvelle variété β-Na9Cr(MoO4)6 de type alluaudite
The title compound, nonasodium chromium(III) hexakis[molybdate(VI)], β-Na9CrMo6O24, was prepared by solid-state reactions. This alluaudite-type structure is constituted of infinite layers formed by links between M 2O10 (M = C/Na) dimers and MoO4 tetra-hedra. The Na(+) and Cr(3+) cations are located in the same site with, respectively, 0.25 and 0.75 occupancies. The layers are connected to each ...
متن کاملModélisation et Animation de Matériaux Hautement Déformables en Synthèse d'Images
In this thesis, we are dealing with computer graphics modeling and animation of highlydeformable materials. Our work is aimed at creating virtual physically-based models of mat-ter, able to automatically deform due to interactions with the environment. Coping withlarge deformation is known to be time consuming, so efficiency and visual quality are thekey issues as they can o...
