Materials Data on Lu2Al3Co by Materials Project
Abstract
Lu2CoAl3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu is bonded in a 12-coordinate geometry to four equivalent Lu, three equivalent Co, and nine equivalent Al atoms. There are three shorter (3.28 Å) and one longer (3.30 Å) Lu–Lu bond lengths. All Lu–Co bond lengths are 3.18 Å. There are three shorter (3.05 Å) and six longer (3.18 Å) Lu–Al bond lengths. Co is bonded to six equivalent Lu and six equivalent Al atoms to form CoLu6Al6 cuboctahedra that share corners with twelve equivalent AlLu6Al4Co2 cuboctahedra, edges with six equivalent CoLu6Al6 cuboctahedra, faces with two equivalent CoLu6Al6 cuboctahedra, and faces with eighteen equivalent AlLu6Al4Co2 cuboctahedra. All Co–Al bond lengths are 2.62 Å. Al is bonded to six equivalent Lu, two equivalent Co, and four equivalent Al atoms to form distorted AlLu6Al4Co2 cuboctahedra that share corners with four equivalent CoLu6Al6 cuboctahedra, corners with fourteen equivalent AlLu6Al4Co2 cuboctahedra, edges with six equivalent AlLu6Al4Co2 cuboctahedra, faces with six equivalent CoLu6Al6 cuboctahedra, and faces with twelve equivalent AlLu6Al4Co2 cuboctahedra. There are two shorter (2.65 Å) and two longer (2.79 Å) Al–Al bond lengths.
