KSn 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 Sn(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. Sn(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Sn(1) atoms.
KSn 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 Sn(1) atoms. There are a spread of K(1)-Sn(1) bond distances ranging from 3.79-3.84 Å. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. There are a spread of K(2)-Sn(1) bond distances ranging from 3.71-3.86 Å. Sn(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Sn(1) atoms. There are two shorter (2.96 Å) and one longer (2.97 Å) Sn(1)-Sn(1) bond length.
