Dy(CrGe)2 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 8-coordinate geometry to eight equivalent Ge(1) atoms. Cr(1) is bonded to four equivalent Ge(1) atoms to form a mixture of corner and edge-sharing CrGe4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1), four equivalent Cr(1), and one Ge(1) atom.
