Abstract: | Summary Salts of the anions [SnX5]–, [SnX4Cl, [SnX3Cl2]–, [SnX3]–, [PbX3]–, [SbX4]–, [SbX3Cl]–, [SbX2Cl2]–, [BiX4]–, [AuCl2]–, [AuX2]–, [AuXCl]–, [AuX4]–, [Au2X6]2– and [PtX4]2–, where X– = C6F5S–, have been isolated and characterised. The neutral SbX3 and BiX3 species, have also been isolated and shown to be pyramidal monomers (19F.n.m.r., i.r., and Raman spectral evidence). Various physical properties of the complexes prepared, as well as their stereochemistries (where these could be ascertained), are similar to those of the known corresponding halogeno compounds of these elements. These results further demonstrate the pseudo-halide nature of the pentafluorothiophenoxide ion.Author to whom all correspondence should be directed at: Laboratoire de Chimie de Coordination, Uniyersité Louis Pasteur, 67008 Strasbourg, France. |
