MgBi3 crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of face and corner-sharing MgBi12 cuboctahedra. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms.
MgBi3 crystallizes in the hexagonal P6_3/mmc space group. Mg(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of face and corner-sharing MgBi12 cuboctahedra. There are six shorter (3.40 Å) and six longer (3.50 Å) Mg(1)-Bi(1) bond lengths. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Mg(1) atoms.
