RbFeAgF6 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. Fe(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form FeF6 octahedra that share corners with two equivalent Fe(1)F6 octahedra and corners with four equivalent Ag(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 23-65°. 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 Fe(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 49-65°. There are four inequivalent F sites. In the first F site, F(4) is bonded in a distorted bent 120 degrees geometry to one Rb(1) and two equivalent Ag(1) atoms. In the second F site, F(1) is bonded in a 3-coordinate geometry to one Rb(1), one Fe(1), and one Ag(1) atom. In the third F site, F(2) is bonded in a bent 150 degrees geometry to two equivalent Fe(1) atoms. In the fourth F site, F(3) is bonded to two equivalent Rb(1), one Fe(1), and one Ag(1) atom to form a mixture of distorted corner and edge-sharing FRb2FeAg tetrahedra.
