Abstract
Co4Al crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are seven inequivalent Co sites. In the first Co site, Co is bonded to nine Co and three equivalent Al atoms to form distorted CoAl3Co9 cuboctahedra that share corners with twelve CoAl3Co9 cuboctahedra, edges with six equivalent AlAl6Co6 cuboctahedra, edges with eighteen CoAl3Co9 cuboctahedra, faces with six equivalent AlAl6Co6 cuboctahedra, and faces with twelve CoAl3Co9 cuboctahedra. There are three shorter (2.45 Å) and six longer (2.58 Å) Co–Co bond lengths. All Co–Al bond lengths are 2.52 Å. In the second Co site, Co is bonded to twelve Co atoms to form CoCo12 cuboctahedra that share corners with three equivalent AlAl6Co6 cuboctahedra, corners with nine CoAl3Co9 cuboctahedra, edges with three equivalent AlAl6Co6 cuboctahedra, edges with twenty-one CoAl3Co9 cuboctahedra, and faces with eighteen CoAl3Co9 cuboctahedra. There are three shorter (2.50 Å) and six longer (2.58 Å) Co–Co bond lengths. In the third Co site, Co is bonded to twelve Co atoms to form CoCo12 cuboctahedra that share corners with three equivalent AlAl6Co6 cuboctahedra, corners with nine CoAl3Co9 cuboctahedra, edges with three equivalent AlAl6Co6 cuboctahedra, edges with twenty-one CoAl3Co9 cuboctahedra, and faces with eighteen CoAl3Co9 cuboctahedra.
