Materials Data on Ho2Co17 by Materials Project
Ho2Co17 crystallizes in the hexagonal P6_3/mmc 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 eighteen Co atoms. There are a spread of Ho–Co bond distances ranging from 2.93–3.25 Å. In the second Ho site, Ho is bonded in a 2-coordinate geometry to twenty Co atoms. There are a spread of Ho–Co bond distances ranging from 2.88–3.13 Å. There are four inequivalent Co sites. In the first Co site, Co is bonded in a 2-coordinate geometry to one Ho and thirteen Co atoms. There are a spread of Co–Co bond distances ranging from 2.32–2.67 Å. In the second Co site, Co is bonded to two equivalent Ho and ten Co atoms to form CoHo2Co10 cuboctahedra that share corners with fourteen CoHo2Co10 cuboctahedra, edges with six equivalent CoHo3Co9 cuboctahedra, and faces with ten CoHo2Co10 cuboctahedra. There are four shorter (2.39 Å) and four longer (2.40 Å) Co–Co bond lengths. In the third Co site, Co is bonded in a 12-coordinate geometry to two Ho and ten Co atoms. There are a spread of Co–Co bond distances ranging from 2.34–2.54 Å. In the fourth Co site, Co is bonded to three Ho and nine Co atoms to form a mixture of distorted face, edge, and corner-sharing CoHo3Co9 cuboctahedra. Both Co–Co bond lengths are 2.41 Å.
