Caesium hexafluoridoiridate(IV)

Cs2[IrF6] possesses a framework structure constructed from Cs+ cations and [IrF6]2− complex anions. The cation is 12-coordinated by F atoms, forming a slightly distorted anti­cubocta­hedron; the anion has the shape of an almost ideal octa­hedron. Cs, Ir and F atoms are located on special positions of 3m, \overline{3}m and m symmetry, respectively.
