The structure described by K3Bi is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 1-coordinate geometry to four equivalent Bi(1) atoms. In the second K site, K(2) is bonded in a trigonal planar geometry to three equivalent Bi(1) atoms. Bi(1) is bonded in a 11-coordinate geometry to three equivalent K(2) and eight equivalent K(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
