N. Matsushita, A. Tanaka and N. Kojima

Abstract: Rb₂[Au^II₂][Au^IIII₄], dirubidium diiodoaurate(I) tetraiodoaurate(III), has a tilted and distorted perovskite-type structure which is isotypic with its bromide analogue Rb₂[Au^IBr₂][Au^IIIBr₄]. The structure contains compressed and elongated [AuI₆] octahedra tilted away from each other and stacked alternately along the [001], [10] and [110] directions by sharing all the corner I^- ions.
