DyRh2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Dy is bonded in a 12-coordinate geometry to twelve equivalent Rh atoms. All Dy–Rh bond lengths are 3.13 Å. Rh is bonded to six equivalent Dy and six equivalent Rh atoms to form a mixture of face, edge, and corner-sharing RhDy6Rh6 cuboctahedra. All Rh–Rh bond lengths are 2.67 Å.
DyRh is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Dy is bonded in a body-centered cubic geometry to eight equivalent Rh atoms. All Dy–Rh bond lengths are 2.97 Å. Rh is bonded in a body-centered cubic geometry to eight equivalent Dy atoms.
DyRh5 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Dy is bonded in a distorted hexagonal planar geometry to eighteen Rh atoms. There are six shorter (3.03 Å) and twelve longer (3.40 Å) Dy–Rh bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded to four equivalent Dy and eight Rh atoms to form a mixture of edge, corner, and face-sharing RhDy4Rh8 cuboctahedra. There are four shorter (2.62 Å) and four longer (2.64 Å) Rh–Rh bond lengths. In the second Rh site, Rh is bonded in a 12-coordinate geometry to three equivalent Dy and nine Rh atoms. All Rh–Rh bond lengths are 3.03 Å.
