MgBi crystallizes in the monoclinic C2 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent Bi(1) and two equivalent Bi(2) 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. There are two 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(1) atoms. In the second Bi site, Bi(2) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(2) atoms.
MgBi crystallizes in the monoclinic C2 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to two equivalent Bi(1) and two equivalent Bi(2) atoms. There is one shorter (3.23 Å) and one longer (3.26 Å) Mg(1)-Bi(1) bond length. There is one shorter (3.14 Å) and one longer (3.16 Å) Mg(1)-Bi(2) bond length. 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. Both Mg(2)-Bi(1) bond lengths are 3.10 Å. There are two shorter (3.21 Å) and two longer (3.40 Å) Mg(2)-Bi(2) bond lengths. There are two 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(1) atoms. In the second Bi site, Bi(2) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(2) atoms.
