Preparation of ferrocenium phosphorus, arsenic, antimony, and bismuth halides. The structure of ferrocenium tetrachlorobismuthate

Abstract

Eleven ferrocenium halogenopentelides (P, As, Sb, or Bi) have been prepared by the reaction of a group 5 element halide with ferrocene in an organic solvent; the structure of one of the products, [Fe(η5-C5H5)2][BiCl4], determined by X-ray crystallography, reveals an extended, one-dimensional anion of irregular, edgesharing BiCl63– octahedra.
