The material structure described by Dy7Rh3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. In the second Dy site, Dy(3) is bonded in a distorted water-like geometry to two equivalent Rh(1) atoms. In the third Dy site, Dy(2) is bonded in a 3-coordinate geometry to three equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to one Dy(1), two equivalent Dy(3), and three equivalent Dy(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
