Dy2Co2Al crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. Co(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), one Co(1), and two equivalent Al(1) atoms. Al(1) is bonded to four equivalent Co(1) atoms to form distorted edge-sharing AlCo4 cuboctahedra.
Dy2Co2Al crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 6-coordinate geometry to six equivalent Co(1) atoms. There are two shorter (2.88 Å) and four longer (2.89 Å) Dy(1)-Co(1) bond lengths. Co(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1), one Co(1), and two equivalent Al(1) atoms. The Co(1)-Co(1) bond length is 2.38 Å. Both Co(1)-Al(1) bond lengths are 2.51 Å. Al(1) is bonded to four equivalent Co(1) atoms to form distorted edge-sharing AlCo4 cuboctahedra.
