DyGa3 crystallizes in the hexagonal P6_3/mmc space group. Dy(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of distorted corner and face-sharing DyGa12 cuboctahedra. Ga(1) is bonded in a 10-coordinate geometry to four equivalent Dy(1) and six equivalent Ga(1) atoms.
DyGa3 crystallizes in the hexagonal P6_3/mmc space group. Dy(1) is bonded to twelve equivalent Ga(1) atoms to form a mixture of distorted corner and face-sharing DyGa12 cuboctahedra. There are six shorter (3.03 Å) and six longer (3.14 Å) Dy(1)-Ga(1) bond lengths. Ga(1) is bonded in a 10-coordinate geometry to four equivalent Dy(1) and six equivalent Ga(1) atoms. There are two shorter (2.73 Å) and four longer (2.74 Å) Ga(1)-Ga(1) bond lengths.
