CsRb2PdF5 crystallizes in the tetragonal P4/mbm space group. Cs(1) is bonded in a distorted q6 geometry to two equivalent F(2) and eight equivalent F(1) atoms. Rb(1) is bonded in a 8-coordinate geometry to two equivalent F(2) and six equivalent F(1) atoms. Pd(1) is bonded in a square co-planar geometry to four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 6-coordinate geometry to two equivalent Cs(1), three equivalent Rb(1), and one Pd(1) atom. In the second F site, F(2) is bonded to two equivalent Cs(1) and four equivalent Rb(1) atoms to form corner-sharing FCs2Rb4 octahedra. The corner-sharing octahedral tilt angles range from 0-32°.
