DyNi2P2 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 16-coordinate geometry to eight equivalent Ni(1) and eight equivalent P(1) atoms. Ni(1) is bonded to four equivalent Dy(1) and four equivalent P(1) atoms to form a mixture of distorted corner, edge, and face-sharing NiDy4P4 tetrahedra. P(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1), four equivalent Ni(1), and one P(1) atom.
