Title: Materials Data on Lu2Ga5Ni12 by Materials Project

Abstract

Lu2Ni12Ga5 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded in a 6-coordinate geometry to eighteen Ni atoms. There are a spread of Lu–Ni bond distances ranging from 2.86–3.26 Å. In the second Lu site, Lu is bonded in a 8-coordinate geometry to twelve Ni and eight Ga atoms. There are six shorter (2.93 Å) and six longer (3.12 Å) Lu–Ni bond lengths. There are two shorter (2.96 Å) and six longer (3.18 Å) Lu–Ga bond lengths. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded to two Lu, six Ni, and four Ga atoms to form distorted NiLu2Ga4Ni6 cuboctahedra that share corners with four equivalent GaLu2Ga2Ni8 cuboctahedra, corners with twenty NiLu2Ga4Ni6 cuboctahedra, edges with two equivalent GaLu2Ga2Ni8 cuboctahedra, edges with three NiLu3Ga3Ni6 cuboctahedra, faces with four equivalent GaLu2Ga2Ni8 cuboctahedra, and faces with seventeen NiLu2Ga4Ni6 cuboctahedra. There are a spread of Ni–Ni bond distances ranging from 2.52–2.67 Å. There are two shorter (2.47 Å) and two longer (2.86 Å) Ni–Ga bond lengths. In the second Ni site, Ni is bonded to three Lu, six Ni, and three Ga atomsmore » to form distorted NiLu3Ga3Ni6 cuboctahedra that share corners with five equivalent GaLu2Ga2Ni8 cuboctahedra, corners with eighteen NiLu3Ga3Ni6 cuboctahedra, edges with three equivalent GaLu2Ga2Ni8 cuboctahedra, edges with seven NiLu3Ga3Ni6 cuboctahedra, faces with two equivalent GaLu2Ga2Ni8 cuboctahedra, and faces with eighteen NiLu2Ga4Ni6 cuboctahedra. Both Ni–Ni bond lengths are 2.43 Å. There are two shorter (2.42 Å) and one longer (2.62 Å) Ni–Ga bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 5-coordinate geometry to one Lu, nine Ni, and four Ga atoms. There are one shorter (2.37 Å) and three longer (2.58 Å) Ga–Ga bond lengths. In the second Ga site, Ga is bonded to two equivalent Lu, eight Ni, and two equivalent Ga atoms to form distorted GaLu2Ga2Ni8 cuboctahedra that share corners with four equivalent GaLu2Ga2Ni8 cuboctahedra, corners with eighteen NiLu3Ga3Ni6 cuboctahedra, edges with ten NiLu3Ga3Ni6 cuboctahedra, faces with six equivalent GaLu2Ga2Ni8 cuboctahedra, and faces with twelve NiLu2Ga4Ni6 cuboctahedra.« less
