The compound described by GeCs crystallizes in the tetragonal I4_1/acd space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. In the second Cs site, Cs(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 10-coordinate geometry to three equivalent Cs(2), four equivalent Cs(1), and three equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
