GdBi3 crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of corner and face-sharing GdBi12 cuboctahedra. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Gd(1) atoms.
GdBi3 crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded to twelve equivalent Bi(1) atoms to form a mixture of corner and face-sharing GdBi12 cuboctahedra. There are six shorter (3.43 Å) and six longer (3.52 Å) Gd(1)-Bi(1) bond lengths. Bi(1) is bonded in a 4-coordinate geometry to four equivalent Gd(1) atoms.
