Title: Materials Data on Dy2Ni17 by Materials Project

Abstract

Dy2Ni17 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 12-coordinate geometry to eighteen Ni atoms. There are a spread of Dy–Ni bond distances ranging from 2.89–3.21 Å. In the second Dy site, Dy is bonded in a 8-coordinate geometry to twenty Ni atoms. There are a spread of Dy–Ni bond distances ranging from 2.83–3.11 Å. There are four inequivalent Ni sites. In the first Ni site, Ni is bonded in a 2-coordinate geometry to one Dy and thirteen Ni atoms. There are a spread of Ni–Ni bond distances ranging from 2.37–2.70 Å. In the second Ni site, Ni is bonded to two equivalent Dy and ten Ni atoms to form NiDy2Ni10 cuboctahedra that share corners with fourteen NiDy2Ni10 cuboctahedra, edges with six equivalent NiDy3Ni9 cuboctahedra, and faces with ten NiDy2Ni10 cuboctahedra. There are four shorter (2.38 Å) and four longer (2.39 Å) Ni–Ni bond lengths. In the third Ni site, Ni is bonded in a 12-coordinate geometry to two Dy and ten Ni atoms. There are a spread of Ni–Ni bond distances ranging from 2.36–2.51 Å. In the fourth Ni site,more » Ni is bonded to three Dy and nine Ni atoms to form a mixture of distorted edge, corner, and face-sharing NiDy3Ni9 cuboctahedra. Both Ni–Ni bond lengths are 2.38 Å.« less
