CsReF8 crystallizes in the tetragonal P4/nmm space group. Cs(1) is bonded to four equivalent F(1) and eight equivalent F(2) atoms to form distorted edge-sharing CsF12 cuboctahedra. Re(1) is bonded in a 8-coordinate geometry to four equivalent F(1) and four equivalent F(2) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a single-bond geometry to two equivalent Cs(1) and one Re(1) atom. In the second F site, F(1) is bonded in a distorted single-bond geometry to one Cs(1) and one Re(1) atom.
