Dy3Ru2Ge3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. In the second Dy site, Dy(2) is bonded in a 9-coordinate geometry to four equivalent Ru(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Dy(2), four equivalent Dy(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to one Dy(2), five equivalent Dy(1), three equivalent Ru(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Dy(2), four equivalent Dy(1), and two equivalent Ru(1) atoms.
