DyGdMn2 is Heusler structured and crystallizes in the trigonal R3m space group. Dy(1) is bonded in a 8-coordinate geometry to four equivalent Mn(1) and four equivalent Mn(2) atoms. There are three shorter (2.92 Å) and one longer (3.25 Å) Dy(1)-Mn(1) bond length. There are three shorter (2.92 Å) and one longer (3.25 Å) Dy(1)-Mn(2) bond length. Gd(1) is bonded in a distorted single-bond geometry to one Mn(2) and four equivalent Mn(1) atoms. The Gd(1)-Mn(2) bond length is 2.22 Å. There are three shorter (2.92 Å) and one longer (3.25 Å) Gd(1)-Mn(1) bond length. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a distorted body-centered cubic geometry to four equivalent Dy(1) and four equivalent Gd(1) atoms. In the second Mn site, Mn(2) is bonded in a distorted single-bond geometry to four equivalent Dy(1) and one Gd(1) atom.
