BiRb is Magnesium tetraboride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Rb sites. In the first Rb site, Rb is bonded in a 6-coordinate geometry to six Bi atoms. There are a spread of Rb–Bi bond distances ranging from 3.76–4.13 Å. In the second Rb site, Rb is bonded in a 7-coordinate geometry to seven Bi atoms. There are a spread of Rb–Bi bond distances ranging from 3.80–4.29 Å. In the third Rb site, Rb is bonded in a 7-coordinate geometry to seven Bi atoms. There are a spread of Rb–Bi bond distances ranging from 3.79–4.35 Å. In the fourth Rb site, Rb is bonded in a 6-coordinate geometry to six Bi atoms. There are a spread of Rb–Bi bond distances ranging from 3.78–4.13 Å. There are four inequivalent Bi sites. In the first Bi site, Bi is bonded in a 9-coordinate geometry to seven Rb and two equivalent Bi atoms. There are one shorter (3.07 Å) and one longer (3.10 Å) Bi–Bi bond lengths. In the second Bi site, Bi is bonded in a 8-coordinate geometry to six Rb and two equivalent Bi atoms. In the third Bi site, Bi is bonded in a 9-coordinate geometry to seven Rb and two equivalent Bi atoms. There are one shorter (3.06 Å) and one longer (3.08 Å) Bi–Bi bond lengths. In the fourth Bi site, Bi is bonded in a 8-coordinate geometry to six Rb and two equivalent Bi atoms.
