The material structure described by CsK3 crystallizes in the tetragonal I4/mmm space group. Cs(1) is bonded to four equivalent K(2) and eight equivalent K(1) atoms to form a mixture of face, corner, and edge-sharing CsK12 cuboctahedra. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 4-coordinate geometry to four equivalent Cs(1) atoms. In the second K site, K(2) is bonded in a square co-planar geometry to four equivalent Cs(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
