The material described by Dy3Pt2Ga9 crystallizes in the orthorhombic Immm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Ga(3) and eight equivalent Ga(2) atoms to form distorted DyGa12 cuboctahedra that share edges with two equivalent Ga(1)Dy4Ga4Pt4 cuboctahedra and faces with two equivalent Dy(1)Ga12 cuboctahedra. In the second Dy site, Dy(2) is bonded in a 12-coordinate geometry to two equivalent Pt(1), two equivalent Ga(1), four equivalent Ga(2), and six equivalent Ga(3) atoms. Pt(1) is bonded in a 10-coordinate geometry to two equivalent Dy(2), two equivalent Ga(1), two equivalent Ga(2), and four equivalent Ga(3) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to four equivalent Dy(2), four equivalent Pt(1), and four equivalent Ga(3) atoms to form GaDy4Ga4Pt4 cuboctahedra that share edges with two equivalent Dy(1)Ga12 cuboctahedra and faces with two equivalent Ga(1)Dy4Ga4Pt4 cuboctahedra. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Dy(1), two equivalent Dy(2), one Pt(1), one Ga(2), and three equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to one Dy(1), three equivalent Dy(2), two equivalent Pt(1), one Ga(1), and three equivalent Ga(2) atoms. is represented by the CIF card [CIF]
