Dy(PtGe)2 crystallizes in the tetragonal P4/nmm space group. Dy(1) is bonded in a 16-coordinate geometry to four equivalent Pt(1), four equivalent Pt(2), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1), one Ge(1), and four equivalent Ge(2) atoms. In the second Pt site, Pt(2) is bonded in a 4-coordinate geometry to four equivalent Dy(1) and four equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1), one Pt(1), and four equivalent Pt(2) atoms. In the second Ge site, Ge(2) is bonded to four equivalent Dy(1) and four equivalent Pt(1) atoms to form a mixture of distorted edge and face-sharing GeDy4Pt4 tetrahedra.
