Materials Data on HoAlNi by Materials Project
Abstract
HoNiAl crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 12-coordinate geometry to three equivalent Ho, five Ni, and seven Al atoms. There are two shorter (3.23 Å) and one longer (3.25 Å) Ho–Ho bond lengths. There are a spread of Ho–Ni bond distances ranging from 2.92–3.20 Å. There are a spread of Ho–Al bond distances ranging from 3.11–3.19 Å. In the second Ho site, Ho is bonded in a 12-coordinate geometry to four Ho, seven Ni, and five Al atoms. The Ho–Ho bond length is 2.99 Å. There are a spread of Ho–Ni bond distances ranging from 3.03–3.12 Å. There are a spread of Ho–Al bond distances ranging from 3.04–3.16 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded to six Ho and six Al atoms to form NiHo6Al6 cuboctahedra that share corners with four equivalent AlHo6Al2Ni4 cuboctahedra, corners with fourteen NiHo6Al6 cuboctahedra, edges with six NiHo6Al6 cuboctahedra, faces with four equivalent NiHo6Al2Ni4 cuboctahedra, and faces with fourteen AlHo6Al2Ni4 cuboctahedra. There are a spread of Ni–Al bond distances ranging from 2.61–2.71 Å. In the secondmore »
