Synthesis and structural characterization of a hydrated sodium–caesium tetracosatungstate(VI), Na5Cs19[W24O84]·21H2O
Crystal formation of pentasodium nonadecacesium tetracosatungstate(VI) heneikosahydrate, Na5Cs19[W24O84]·21H2O, was successfully achieved by the conversion of [H2W12O42]10– through the addition of excess Cs+. The crystal structure comprising the toroidal isopolyoxidometalate is presented, as well as its Raman spectrum. Na5Cs19(H2O)21W24O84 crystallizes in the rhombohedral space group R$$\overline{3}$$ with an obverse centering. The title compound represents the addition of a new member to the isopolytungstate family with mixed alkali counter-ions and contains rarely observed five-coordinate tungsten(VI) atoms in the [W24O84]24– anion (site symmetry C3i) arising from the conversion mediated by Cs+ counter-ions.
