GdGa3 crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of distorted face and corner-sharing GdGa12 cuboctahedra. Ga(1) is bonded in a 10-coordinate geometry to four equivalent Gd(1) and six equivalent Ga(1) atoms.
GdGa3 crystallizes in the hexagonal P6_3/mmc space group. Gd(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of distorted face and corner-sharing GdGa12 cuboctahedra. There are six shorter (3.06 Å) and six longer (3.17 Å) Gd(1)-Ga(1) bond lengths. Ga(1) is bonded in a 10-coordinate geometry to four equivalent Gd(1) and six equivalent Ga(1) atoms. There are two shorter (2.73 Å) and four longer (2.75 Å) Ga(1)-Ga(1) bond lengths.
