Materials Data on Rb2GdAgCl6 by Materials Project
Rb2GdAgCl6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. 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 GdCl6 octahedra, and faces with four equivalent AgCl6 octahedra. All Rb–Cl bond lengths are 3.83 Å. Gd3+ is bonded to six equivalent Cl1- atoms to form GdCl6 octahedra that share corners with six equivalent AgCl6 octahedra and faces with eight equivalent RbCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Gd–Cl bond lengths are 2.66 Å. Ag1+ is bonded to six equivalent Cl1- atoms to form AgCl6 octahedra that share corners with six equivalent GdCl6 octahedra and faces with eight equivalent RbCl12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–Cl bond lengths are 2.75 Å. Cl1- is bonded in a distorted linear geometry to four equivalent Rb1+, one Gd3+, and one Ag1+ atom.
