DyCo2Ge2 crystallizes in the tetragonal I4/mmm space group. Dy(1) is bonded in a 16-coordinate geometry to eight equivalent Co(1) and eight equivalent Ge(1) atoms. Co(1) is bonded to four equivalent Dy(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge, corner, and face-sharing CoDy4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1), four equivalent Co(1), and one Ge(1) atom.
