Dy3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 9-coordinate geometry to four equivalent Rh(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. In the second Dy site, Dy(2) is bonded in a 8-coordinate geometry to four equivalent Rh(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Dy(1), four equivalent Dy(2), one Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1), four equivalent Dy(2), and two equivalent Rh(1) atoms. In the second Ge site, Ge(2) is bonded in a 12-coordinate geometry to two equivalent Dy(1), six equivalent Dy(2), and four equivalent Rh(1) atoms.

In the first Dy site, Dy(1) is bonded in a 9-coordinate geometry to four equivalent Rh(1), two equivalent Ge(2), and three equivalent Ge(1) atoms. There are two shorter (3.02 Å) and two longer (3.04 Å) Dy(1)-Rh(1) bond lengths. Both Dy(1)-Ge(2) bond lengths are 3.31 Å. There are two shorter (3.00 Å) and one longer (3.04 Å) Dy(1)-Ge(1) bond length. In the second Dy site, Dy(2) is bonded in a 8-coordinate geometry to four equivalent Rh(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. There are a spread of Dy(2)-Rh(1) bond distances ranging from 2.87-3.10 Å. There is one shorter (2.96 Å) and one longer (3.02 Å) Dy(2)-Ge(1) bond length. There are a spread of Dy(2)-Ge(2) bond distances ranging from 3.20-3.35 Å.
