K3Bi2 crystallizes in the monoclinic C2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent Bi(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Bi(1) atoms. Bi(1) is bonded in a 10-coordinate geometry to three equivalent K(2), six equivalent K(1), and one Bi(1) atom.
K3Bi2 crystallizes in the monoclinic C2/c space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent Bi(1) atoms. There are a spread of K(1)-Bi(1) bond distances ranging from 3.63-3.96 Å. In the second K site, K(2) is bonded in a 6-coordinate geometry to six equivalent Bi(1) atoms. There are a spread of K(2)-Bi(1) bond distances ranging from 3.73-3.95 Å. Bi(1) is bonded in a 10-coordinate geometry to three equivalent K(2), six equivalent K(1), and one Bi(1) atom. The Bi(1)-Bi(1) bond length is 2.98 Å.
