The crystal structure described by Dy2Pt is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to four equivalent Pt(1) atoms to form a mixture of edge and corner-sharing DyPt4 tetrahedra. In the second Dy site, Dy(2) is bonded in a 3-coordinate geometry to three equivalent Pt(1) atoms. Pt(1) is bonded in a 7-coordinate geometry to three equivalent Dy(2) and four equivalent Dy(1) atoms. is represented by the CIF file [CIF]
