Materials Data on Rb(In3Au2)2 by Materials Project

Abstract

Rb(Au2In3)2 crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Rb is bonded to six equivalent Au and six equivalent In atoms to form face-sharing RbIn6Au6 cuboctahedra. All Rb–Au bond lengths are 3.74 Å. All Rb–In bond lengths are 3.65 Å. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 6-coordinate geometry to two equivalent Rb and six In atoms. There are two shorter (2.91 Å) and four longer (2.94 Å) Au–In bond lengths. In the second Au site, Au is bonded in a 9-coordinate geometry to nine In atoms. There are three shorter (2.90 Å) and six longer (3.00 Å) Au–In bond lengths. There are two inequivalent In sites. In the first In site, In is bonded in a 5-coordinate geometry to five Au atoms. In the second In site, In is bonded in a 4-coordinate geometry to two equivalent Rb and four Au atoms.
