The crystal structure described by Dy5Rh3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to six equivalent Rh(1) atoms to form a mixture of distorted corner, edge, and face-sharing DyRh6 octahedra. The corner-sharing octahedral tilt angles are 35°. In the second Dy site, Dy(2) is bonded in a 5-coordinate geometry to five equivalent Rh(1) atoms. Rh(1) is bonded in a 9-coordinate geometry to four equivalent Dy(1) and five equivalent Dy(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
