Dy2Ge3 crystallizes in the hexagonal P-6m2 space group. Dy(1) is bonded in a 9-coordinate geometry to three equivalent Ge(1), three equivalent Ge(2), and three equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to six equivalent Dy(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent Ge(1) atoms.
