RbAgF3 is (Cubic) Perovskite structured and crystallizes in the orthorhombic Amm2 space group. Rb(1) is bonded to four equivalent F(2) and eight equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with twelve equivalent Rb(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, and faces with eight equivalent Ag(1)F6 octahedra. Ag(1) is bonded to two equivalent F(2) and four equivalent F(1) atoms to form AgF6 octahedra that share corners with six equivalent Ag(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent F sites. In the first F site, F(1) is bonded to four equivalent Rb(1) and two equivalent Ag(1) atoms to form a mixture of distorted edge, corner, and face-sharing FRb4Ag2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°. In the second F site, F(2) is bonded to four equivalent Rb(1) and two equivalent Ag(1) atoms to form a mixture of distorted edge, corner, and face-sharing FRb4Ag2 octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
