The material described by Dy3Ge4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 8-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), and four equivalent Ge(2) atoms. In the second Dy site, Dy(2) is bonded in a 7-coordinate geometry to three equivalent Ge(1) and four equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Dy(2), four equivalent Dy(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), one Ge(1), and two equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 4-coordinate geometry to four equivalent Dy(1) and four equivalent Ge(2) atoms. is represented by the CIF card [CIF]
