Abstract

Single-Crystal Structure Determination of NO 2SbF6, XeF5SbF6 and XeF5Sb2F11. -The title compounds are prepared according to the literature and used for single crystal growth in a T-shaped fluoroethylene-hexafluoropropylene crystallization apparatus. Anhydrous HF is condensed on the solids at 77 K prior to being warmed up to 25 C for slow HF evaporation (2 months). NO 2SbF6 crystallizes in the orthorhombic space group Cmmm (Z = 2, single crystal XRD, 150 K) and exhibits a different packing of the [NO 2] + and [SbF6]ions than that in NO2AsF6. The XeF5SbF6 compound crystallizes in the orthorhombic space group Pnma (Z = 4, 150 K) and is isotypic with the known XeF5MF6 structures (M: Nb, Ru, Pt). XeF5Sb2F11 is triclinic (space group P1, Z = 2, 200 K) with each [XeF 5] + cation having four interactions with the three [Sb2F11]anions. -(MAZEJ*, Z.; GORESHNIK, E. A.; J.
