The crystal structure described by Dy2Pd2Si crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 9-coordinate geometry to three equivalent Pd(1), four equivalent Pd(2), and two equivalent Si(1) atoms. In the second Dy site, Dy(2) is bonded in a 9-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), and four equivalent Si(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to three equivalent Dy(1), three equivalent Dy(2), and one Si(1) atom. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), one Pd(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), one Pd(1), two equivalent Pd(2), and one Si(1) atom. is represented by the CIF file [CIF]
