Abstract
YNiAl crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 12-coordinate geometry to three equivalent Y, five Ni, and seven Al atoms. There are one shorter (3.15 Å) and two longer (3.25 Å) Y–Y bond lengths. There are a spread of Y–Ni bond distances ranging from 2.95–3.11 Å. There are a spread of Y–Al bond distances ranging from 3.07–3.23 Å. In the second Y site, Y is bonded in a 12-coordinate geometry to four Y, seven Ni, and five Al atoms. The Y–Y bond length is 3.14 Å. There are a spread of Y–Ni bond distances ranging from 3.00–3.15 Å. There are a spread of Y–Al bond distances ranging from 3.12–3.16 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded to six Y, four Ni, and two equivalent Al atoms to form distorted NiY6Al2Ni4 cuboctahedra that share corners with eight NiY6Al2Ni4 cuboctahedra, corners with ten AlY6Al4Ni2 cuboctahedra, edges with two equivalent NiY6Al2Ni4 cuboctahedra, edges with four equivalent AlY6Al4Ni2 cuboctahedra, faces with eight AlY6Al4Ni2 cuboctahedra, and faces with ten NiY6Al2Ni4 cuboctahedra. There are a spread of Ni–Nimore »
