The structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
