Abstract

The title potassium vanadium tungsten bis-(arsenate oxide) was synthesized by a solid-state reaction at 973 K. The crystal structure is isotypic with KVOPO(4) and contains a [MVAs(2)O(10)](∞) framework built up from single MO(6) (M = V+W) octa-hedra sharing corners with single VO(6) octa-hedra and AsO(4) tetra-hedra. This structure shows the existence of infinite [VAsO(8)](∞) and [MAsO(8)](∞) chains running along the a and c directions, respectively. All atoms are located on general positions. The metal position M is statistically occupied by 78% V and 22% W.

La phase KVOPO4 a été décrite en premier par Benhamada et al. (1991 ▶). Quant à l’étude de la propriété optique du composé KTiOPO4 elle a été réalisée par Phillips et al. (1990 ▶). Les structures isotypes arséniates de formulation MTiOAsO4 (M = métal alcalin) ont été obtenues par réaction à l’état solide (El Haidouri et al., 1990 ▶; Nakagawa et al., 1999 ▶; El Brahimi & Durand, 1986 ▶). Pour la synthèse par la voie hydro­thermale des composés isotypes de formulation MScFAsO4 (M = Rb et Cs), voir Harrison & Phillips (1999 ▶).

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors are based on F, with F set to zero for negative F2. The threshold expression of F2 > n*σ(F2) is used only for calculating R-factors etc. and is not relevant to the choice of reflections for refinement. The program used for refinement, Jana2000, uses the weighting scheme based on the experimental expectations, see _refine_ls_weighting_details, that does not force S to be one. Therefore the values of S are usually larger then the ones from the SHELX program.
