KBi is Magnesium tetraboride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent K sites. In the first K site, K is bonded in a 6-coordinate geometry to six Bi atoms. There are a spread of K–Bi bond distances ranging from 3.64–3.91 Å. In the second K site, K is bonded in a 6-coordinate geometry to seven Bi atoms. There are a spread of K–Bi bond distances ranging from 3.67–4.13 Å. In the third K site, K is bonded in a 7-coordinate geometry to seven Bi atoms. There are a spread of K–Bi bond distances ranging from 3.68–4.07 Å. In the fourth K site, K is bonded in a 6-coordinate geometry to six Bi atoms. There are a spread of K–Bi bond distances ranging from 3.65–3.92 Å. There are four inequivalent Bi sites. In the first Bi site, Bi is bonded in a 9-coordinate geometry to seven K and two equivalent Bi atoms. There are one shorter (3.06 Å) and one longer (3.11 Å) Bi–Bi bond lengths. In the second Bi site, Bi is bonded in a 8-coordinate geometry to six K and two equivalent Bi atoms. In the third Bi site, Bi is bonded in a 9-coordinate geometry to seven K and two equivalent Bi atoms. Both Bi–Bi bond lengths are 3.07 Å. In the fourth Bi site, Bi is bonded in a 8-coordinate geometry to six K and two equivalent Bi atoms.
