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