  Preparation and Structures of Salts with the Anions of IF2?, ClF4? IF4?, TeF7?, and AsF4?

  摘要：

  AbstractSingle crystal structures are presented for the IF2−, ClF4−, IF4−, TeF7−, and AsF4− fluoroanions. The 1,1,3,3,5,5 hexamethylpiperidinium (pip+) ion was used as cation in order to obtain good crystallinity and to avoid twinning and disorder which are notorious with the tetramethylammonium ion. Precise structural data are obtained for the first time, and the ions have the expected geometries. The pip+ has the further advantage that cation‐anion interactions are weak, which results in fairly ideal structures of the anions. Pip+BrF2− is too unstable to be obtained in single crystal form, and pip+BrOF4− as well as NO+BrOF4− show disordered anions and cations.
