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.
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. There are a spread of K(1)-Ge(1) bond distances ranging from 3.53-3.63 Å. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. There are a spread of K(2)-Ge(1) bond distances ranging from 3.50-3.66 Å. Ge(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Ge(1) atoms. There are two shorter (2.57 Å) and one longer (2.58 Å) Ge(1)-Ge(1) bond length.
