The material structure described by Dy2Co3Al crystallizes in the trigonal R-3m space group. Dy(1) is bonded in a 16-coordinate geometry to four equivalent Dy(1), nine equivalent Co(1), and three equivalent Al(1) atoms. Co(1) is bonded to six equivalent Dy(1), four equivalent Co(1), and two equivalent Al(1) atoms to form distorted CoDy6Al2Co4 cuboctahedra that share corners with four equivalent Al(1)Dy6Co6 cuboctahedra, corners with fourteen equivalent Co(1)Dy6Al2Co4 cuboctahedra, edges with six equivalent Co(1)Dy6Al2Co4 cuboctahedra, faces with six equivalent Al(1)Dy6Co6 cuboctahedra, and faces with twelve equivalent Co(1)Dy6Al2Co4 cuboctahedra. Al(1) is bonded to six equivalent Dy(1) and six equivalent Co(1) atoms to form distorted AlDy6Co6 cuboctahedra that share corners with six equivalent Al(1)Dy6Co6 cuboctahedra, corners with twelve equivalent Co(1)Dy6Al2Co4 cuboctahedra, edges with six equivalent Al(1)Dy6Co6 cuboctahedra, and faces with eighteen equivalent Co(1)Dy6Al2Co4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
