Dy2Ni2Al crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Al(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), one Ni(1), and two equivalent Al(1) atoms. Al(1) is bonded to eight equivalent Dy(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and edge-sharing AlDy8Ni4 cuboctahedra.
Dy2Ni2Al crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 10-coordinate geometry to six equivalent Ni(1) and four equivalent Al(1) atoms. There are two shorter (2.83 Å) and four longer (2.95 Å) Dy(1)-Ni(1) bond lengths. There are two shorter (3.16 Å) and two longer (3.21 Å) Dy(1)-Al(1) bond lengths. Ni(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), one Ni(1), and two equivalent Al(1) atoms. The Ni(1)-Ni(1) bond length is 2.49 Å. Both Ni(1)-Al(1) bond lengths are 2.53 Å. Al(1) is bonded to eight equivalent Dy(1) and four equivalent Ni(1) atoms to form a mixture of distorted face and edge-sharing AlDy8Ni4 cuboctahedra.
