Abstract
Trifluoro(methyl)arsonium hexafluoroarsenate was prepared and characterized by Raman spectroscopy and its crystal structure, determined by X-ray diffr action. Trifluoro(methyl)arsonium hexafluoroarsenate crystallises in the mo noclinic space group P2(1)/n (no. 14) with Z = 4 and a = 787.5(1), b = 892. 9(1), c = 1061.4(1) pm, beta = 96.96(1)degrees, V = 0.74083(14) nm(3). The final R factor is 0.0343 for 2009 reflections with I > 2 sigma(I). The cati on has C-3v symmetry and the anion shapes a distorted octahedron.
