Abstract

An unprecedented molecular AuI3 complex has been stabilized in the interlayer space of the Bi2Sr2CaCu2Oy lattice by reacting Au metal with IBi2Sr2CaCu2Oy. at 235 °C. The stoichiometry of this new intercalate phase is determined as (AuI3)0.25Bi2Sr2CaCu 2Oy by thermogravimetry and X-ray photoelectron spectroscopy. MicroRaman and Au L3-edge extended X-ray absorption fine structure analyses reveal that Au and I are stabilized as the molecular AuI3 (D3h) in the Bi2Sr2CaCu2Oy lattice with a uniform Au-I bond length of 2.56 Å. According to the powder X-ray diffraction pattern analysis, the basal spacing increases from 15.30 to 18.55 Å with an expansion of 3.25 Å implying that the AuI3 molecules are intercalated into the [Bi-O] double layers with a parallel geometry. The present AuI3 entity is the first of the three coordinated molecular Au-complexes to be stabilized in a solid matrix at room temperature.
