The crystal structure described by DyGa3 crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to six equivalent Ga(1) and six equivalent Ga(2) atoms to form a mixture of distorted face and corner-sharing DyGa12 cuboctahedra. In the second Dy site, Dy(2) is bonded to three equivalent Ga(1), three equivalent Ga(3), and six equivalent Ga(2) atoms to form a mixture of face and corner-sharing DyGa12 cuboctahedra. In the third Dy site, Dy(3) is bonded to three equivalent Ga(2) and nine equivalent Ga(3) atoms to form a mixture of distorted face and corner-sharing DyGa12 cuboctahedra. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), two equivalent Ga(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to one Dy(1), one Dy(3), two equivalent Dy(2), two equivalent Ga(1), two equivalent Ga(2), and two equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to one Dy(2), three equivalent Dy(3), two equivalent Ga(2), and four equivalent Ga(3) atoms. is represented by the CIF card [CIF]
