Abstract

The structure of Ba₃W₂O₉ has been determined from powder x-ray diffraction data and found to be the same as in Cs₃Tl₂Cl₉. Two-thirds of the octahedral sites between hexagonal closest-packed BaO₃ layers (ABAB...) are filled by the tungsten atoms. The enneaoxo W₂O₉ ^6- group represents the first crystal chemistry example of tungsten (VI) in a face-sharing arrangement. Infrared and Raman data are consistent with overall 32 (D₃) site symmetry. Crystallographic and spectroscopic evidence supports a covalent bonding model with oxygen pπ → metal dπ stabilization of this tungsten (VI) phase.
