Structural Diversity in Iodoantimonates; the Anions Sb₃I, Sb₅I and Sb₆I

Abstract

An unusual tailoring to the “spatial requirements” of the cation in a crystal is observed with iodoantimonate(III) anions. This is demonstrated by the synthesis of the salts [Cu(MeCN)4]2[Sb3I11], [Me4N]3[Sb5I18] and [Cp2Fe]4[Sb6I22]from SbI3 and the corresponding iodide.
