The material structure described by Dy(PtSi)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 Si(1), and four equivalent Si(2) atoms. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded to four equivalent Dy(1) and four equivalent Si(2) atoms to form distorted PtDy4Si4 tetrahedra that share corners with twelve equivalent Si(1)Dy4Pt4 tetrahedra, edges with two equivalent Si(1)Dy4Pt4 tetrahedra, edges with four equivalent Pt(1)Dy4Si4 tetrahedra, and faces with four equivalent Pt(1)Dy4Si4 tetrahedra. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to four equivalent Dy(1), one Si(2), and four equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to four equivalent Dy(1) and four equivalent Pt(2) atoms to form distorted SiDy4Pt4 tetrahedra that share corners with twelve equivalent Pt(1)Dy4Si4 tetrahedra, edges with two equivalent Pt(1)Dy4Si4 tetrahedra, edges with four equivalent Si(1)Dy4Pt4 tetrahedra, and faces with four equivalent Si(1)Dy4Pt4 tetrahedra. In the second Si site, Si(2) is bonded in a 5-coordinate geometry to four equivalent Dy(1), one Pt(2), and four equivalent Pt(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
