Materials Data on Rb3AuCl6 by Materials Project
Rb3AuCl6 is (Cubic) Perovskite-like structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to twelve equivalent Cl1- atoms to form RbCl12 cuboctahedra that share corners with twelve equivalent RbCl12 cuboctahedra, faces with six equivalent RbCl12 cuboctahedra, faces with four equivalent RbCl6 octahedra, and faces with four equivalent AuCl6 octahedra. All Rb–Cl bond lengths are 3.96 Å. In the second Rb1+ site, Rb1+ is bonded to six equivalent Cl1- atoms to form RbCl6 octahedra that share corners with six equivalent AuCl6 octahedra and faces with eight equivalent RbCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–Cl bond lengths are 3.07 Å. Au3+ is bonded to six equivalent Cl1- atoms to form AuCl6 octahedra that share corners with six equivalent RbCl6 octahedra and faces with eight equivalent RbCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Au–Cl bond lengths are 2.51 Å. Cl1- is bonded in a distorted linear geometry to five Rb1+ and one Au3+ atom.
