DyPd2Si2 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 16-coordinate geometry to eight equivalent Pd(1) and eight equivalent Si(1) atoms. Pd(1) is bonded to four equivalent Dy(1) and four equivalent Si(1) atoms to form a mixture of distorted face, corner, and edge-sharing PdDy4Si4 tetrahedra. Si(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1), four equivalent Pd(1), and one Si(1) atom.
