The material described by DyCo4Al crystallizes in the orthorhombic Cmmm space group. Dy(1) is bonded in a distorted hexagonal planar geometry to six equivalent Co(1), eight equivalent Co(2), and four equivalent Al(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1), four equivalent Co(2), and two equivalent Al(1) atoms. In the second Co site, Co(2) is bonded to four equivalent Dy(1), two equivalent Co(2), four equivalent Co(1), and two equivalent Al(1) atoms to form distorted CoDy4Al2Co6 cuboctahedra that share corners with four equivalent Al(1)Dy4Co8 cuboctahedra, corners with twelve equivalent Co(2)Dy4Al2Co6 cuboctahedra, edges with four equivalent Al(1)Dy4Co8 cuboctahedra, edges with six equivalent Co(2)Dy4Al2Co6 cuboctahedra, faces with four equivalent Al(1)Dy4Co8 cuboctahedra, and faces with six equivalent Co(2)Dy4Al2Co6 cuboctahedra. Al(1) is bonded to four equivalent Dy(1), four equivalent Co(1), and four equivalent Co(2) atoms to form distorted AlDy4Co8 cuboctahedra that share corners with eight equivalent Co(2)Dy4Al2Co6 cuboctahedra, corners with eight equivalent Al(1)Dy4Co8 cuboctahedra, edges with two equivalent Al(1)Dy4Co8 cuboctahedra, edges with eight equivalent Co(2)Dy4Al2Co6 cuboctahedra, faces with two equivalent Al(1)Dy4Co8 cuboctahedra, and faces with eight equivalent Co(2)Dy4Al2Co6 cuboctahedra. is represented by the CIF card [CIF]
