The compound described by RbAgAlF6 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 7-coordinate geometry to one F(4), two equivalent F(1), and four equivalent F(3) atoms. Ag(1) is bonded to two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form AgF6 octahedra that share corners with two equivalent Ag(1)F6 octahedra and corners with four equivalent Al(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 52-63°. Al(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form AlF6 octahedra that share corners with two equivalent Al(1)F6 octahedra and corners with four equivalent Ag(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 18-63°. There are four inequivalent F sites. In the first F site, F(4) is bonded in a distorted trigonal planar geometry to one Rb(1) and two equivalent Ag(1) atoms. In the second F site, F(1) is bonded in a 1-coordinate geometry to one Rb(1), one Ag(1), and one Al(1) atom. In the third F site, F(2) is bonded in a linear geometry to two equivalent Al(1) atoms. In the fourth F site, F(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one Ag(1), and one Al(1) atom. is represented by the CIF card [CIF]
