title: Xenon(II) polyfluoridotitanates(IV): synthesis and structural characterization of [Xe2F3]+ and [XeF]+ salts.
abstract: Thermal reaction between XeF2 and excess TiF4 resulted in the unexpected formation of a highly ionized Xe(II)  species. The products [Xe2F3][Ti8F33] and [XeF]2[Ti9F38] represent the first examples of [Xe2F3](+) and [XeF](+) compounds, which differ from known Xe(II) salts containing discrete fluoride anions with pentavalent metalloid/metal centers. A new structural type of 2D polyanion [Ti8F33](-) and the formation and structure of the novel 1D [Ti9F38](2-) are discussed. Both products were characterized by single-crystal X-ray analysis and Raman spectroscopy.
