The crystal structure described by Dy2CoAl3 crystallizes in the trigonal R-3m space group. Dy(1) is bonded in a 16-coordinate geometry to four equivalent Dy(1), three equivalent Co(1), and nine equivalent Al(1) atoms. Co(1) is bonded to six equivalent Dy(1) and six equivalent Al(1) atoms to form CoDy6Al6 cuboctahedra that share corners with six equivalent Co(1)Dy6Al6 cuboctahedra, corners with twelve equivalent Al(1)Dy6Al4Co2 cuboctahedra, edges with six equivalent Co(1)Dy6Al6 cuboctahedra, and faces with eighteen equivalent Al(1)Dy6Al4Co2 cuboctahedra. Al(1) is bonded to six equivalent Dy(1), two equivalent Co(1), and four equivalent Al(1) atoms to form AlDy6Al4Co2 cuboctahedra that share corners with four equivalent Co(1)Dy6Al6 cuboctahedra, corners with fourteen equivalent Al(1)Dy6Al4Co2 cuboctahedra, edges with six equivalent Al(1)Dy6Al4Co2 cuboctahedra, faces with six equivalent Co(1)Dy6Al6 cuboctahedra, and faces with twelve equivalent Al(1)Dy6Al4Co2 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
