Materials Data on Al5Mo by Materials Project
Al5Mo crystallizes in the hexagonal P6_322 space group. The structure is three-dimensional. there are two inequivalent Mo sites. In the first Mo site, Mo is bonded to twelve Al atoms to form MoAl12 cuboctahedra that share corners with six equivalent MoAl12 cuboctahedra, corners with twelve AlAl9Mo3 cuboctahedra, edges with six equivalent MoAl12 cuboctahedra, edges with twelve AlAl10Mo2 cuboctahedra, and faces with twenty AlAl10Mo2 cuboctahedra. There are six shorter (2.75 Å) and six longer (2.84 Å) Mo–Al bond lengths. In the second Mo site, Mo is bonded to twelve Al atoms to form MoAl12 cuboctahedra that share corners with six equivalent MoAl12 cuboctahedra, corners with twelve AlAl9Mo3 cuboctahedra, edges with six equivalent MoAl12 cuboctahedra, edges with twelve AlAl10Mo2 cuboctahedra, and faces with twenty AlAl10Mo2 cuboctahedra. There are six shorter (2.75 Å) and six longer (2.84 Å) Mo–Al bond lengths. There are six inequivalent Al sites. In the first Al site, Al is bonded to two Mo and ten Al atoms to form distorted AlAl10Mo2 cuboctahedra that share corners with twelve AlAl10Mo2 cuboctahedra, edges with four MoAl12 cuboctahedra, edges with twenty AlAl10Mo2 cuboctahedra, faces with four MoAl12 cuboctahedra, and faces with fourteen AlAl10Mo2 cuboctahedra. There are a spread of Al–Al bond distances ranging from 2.75–2.88 Å. In the second Al site, Al is bonded to two Mo and ten Al atoms to form distorted AlAl10Mo2 cuboctahedra that share corners with twelve AlAl10Mo2 cuboctahedra, edges with four MoAl12 cuboctahedra, edges with twenty AlAl10Mo2 cuboctahedra, faces with four MoAl12 cuboctahedra, and faces with fourteen AlAl10Mo2 cuboctahedra. There are a spread of Al–Al bond distances ranging from 2.75–2.88 Å. In the third Al site, Al is bonded to two Mo and ten Al atoms to form distorted AlAl10Mo2 cuboctahedra that share corners with twelve AlAl10Mo2 cuboctahedra, edges with four MoAl12 cuboctahedra, edges with twenty AlAl10Mo2 cuboctahedra, faces with four MoAl12 cuboctahedra, and faces with fourteen AlAl10Mo2 cuboctahedra. There are a spread of Al–Al bond distances ranging from 2.75–2.88 Å. In the fourth Al site, Al is bonded to three equivalent Mo and nine Al atoms to form distorted AlAl9Mo3 cuboctahedra that share corners with nine MoAl12 cuboctahedra, corners with nine equivalent AlAl9Mo3 cuboctahedra, edges with eighteen AlAl10Mo2 cuboctahedra, faces with three equivalent MoAl12 cuboctahedra, and faces with seventeen AlAl10Mo2 cuboctahedra. There are one shorter (2.77 Å) and three longer (2.84 Å) Al–Al bond lengths. In the fifth Al site, Al is bonded to three equivalent Mo and nine Al atoms to form distorted AlAl9Mo3 cuboctahedra that share corners with three equivalent MoAl12 cuboctahedra, corners with fifteen AlAl9Mo3 cuboctahedra, edges with eighteen AlAl10Mo2 cuboctahedra, faces with five MoAl12 cuboctahedra, and faces with fifteen AlAl10Mo2 cuboctahedra. The Al–Al bond length is 2.75 Å. In the sixth Al site, Al is bonded to two Mo and ten Al atoms to form distorted AlAl10Mo2 cuboctahedra that share corners with twelve AlAl10Mo2 cuboctahedra, edges with four MoAl12 cuboctahedra, edges with twenty AlAl10Mo2 cuboctahedra, faces with four MoAl12 cuboctahedra, and faces with fourteen AlAl10Mo2 cuboctahedra.
