DyGdNi2 crystallizes in the orthorhombic Amm2 space group. Dy(1) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(2) atoms. Gd(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1), four equivalent Gd(1), and two equivalent Ni(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to four equivalent Dy(1), three equivalent Gd(1), and two equivalent Ni(1) atoms.
DyGdNi2 crystallizes in the orthorhombic Amm2 space group. Dy(1) is bonded in a 7-coordinate geometry to three equivalent Ni(1) and four equivalent Ni(2) atoms. There are two shorter (2.83 Å) and one longer (2.99 Å) Dy(1)-Ni(1) bond length. All Dy(1)-Ni(2) bond lengths are 2.88 Å. Gd(1) is bonded in a 7-coordinate geometry to three equivalent Ni(2) and four equivalent Ni(1) atoms. There are two shorter (2.86 Å) and one longer (2.95 Å) Gd(1)-Ni(2) bond length. All Gd(1)-Ni(1) bond lengths are 2.89 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1), four equivalent Gd(1), and two equivalent Ni(2) atoms. Both Ni(1)-Ni(2) bond lengths are 2.54 Å. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to four equivalent Dy(1), three equivalent Gd(1), and two equivalent Ni(1) atoms.
