Structure cristalline de K 2SO 4(SbF 3) 2
Abstract
The crystal structure of K 2SO 4(SbF 3) 2 was determined by X-ray diffraction on a single crystal ( R = 0.035 for 2264 reflections). There are two families of antimony atoms showing two different environments: AX 5E octahedron (6 coordination) and AX 6E 3.3.1 monocapped octahedron (7 coordination). The SO 2-4 unit weakly bonded to four antimony atoms is not very distorted. This arrangement permits the minimization of π-E interactions. Infrared and Raman spectra are discussed in terms of diffraction results.
