The structure described by MgBi crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to two equivalent Bi(2) and four equivalent Bi(3) atoms. In the second Mg site, Mg(2) is bonded in a 6-coordinate geometry to two equivalent Bi(1) and four equivalent Bi(2) atoms. In the third Mg site, Mg(3) is bonded in a distorted body-centered cubic geometry to two equivalent Bi(2), two equivalent Bi(3), and four equivalent Bi(1) atoms. There are three inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 6-coordinate geometry to two equivalent Mg(2) and four equivalent Mg(3) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to two equivalent Mg(1), two equivalent Mg(3), and four equivalent Mg(2) atoms. In the third Bi site, Bi(3) is bonded in a 6-coordinate geometry to two equivalent Mg(3) and four equivalent Mg(1) atoms. is represented by the CIF card [CIF]
