Dy2InGe2 crystallizes in the tetragonal P4/mbm space group. Dy(1) is bonded in a 10-coordinate geometry to four equivalent In(1) and six equivalent Ge(1) atoms. In(1) is bonded to eight equivalent Dy(1) and four equivalent Ge(1) atoms to form a mixture of corner and face-sharing InDy8Ge4 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), two equivalent In(1), and one Ge(1) atom.
