KPb 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 Pb(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. Pb(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Pb(1) atoms.
KPb 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 Pb(1) atoms. There are a spread of K(1)-Pb(1) bond distances ranging from 3.84-3.89 Å. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Pb(1) atoms. There are a spread of K(2)-Pb(1) bond distances ranging from 3.71-3.85 Å. Pb(1) is bonded in a 10-coordinate geometry to three equivalent K(2), four equivalent K(1), and three equivalent Pb(1) atoms. There is one shorter (3.11 Å) and two longer (3.13 Å) Pb(1)-Pb(1) bond lengths.
