Title: Materials Data on Dy2Fe17C3 by Materials Project

Abstract

Dy2Fe17C3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are three inequivalent Dy sites. In the first Dy site, Dy is bonded in a distorted trigonal planar geometry to eight Fe and three equivalent C atoms. There are two shorter (2.99 Å) and six longer (3.25 Å) Dy–Fe bond lengths. All Dy–C bond lengths are 2.51 Å. In the second Dy site, Dy is bonded in a distorted trigonal planar geometry to eight Fe and three equivalent C atoms. There are two shorter (2.99 Å) and six longer (3.25 Å) Dy–Fe bond lengths. All Dy–C bond lengths are 2.51 Å. In the third Dy site, Dy is bonded in a trigonal planar geometry to three equivalent C atoms. All Dy–C bond lengths are 2.48 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded to two Dy and ten Fe atoms to form FeDy2Fe10 cuboctahedra that share corners with four equivalent FeDy2Fe10 cuboctahedra, corners with two equivalent CDy2Fe4 octahedra, faces with six equivalent FeDy2Fe10 cuboctahedra, and faces with four equivalent CDy2Fe4 octahedra. The corner-sharing octahedral tilt angles are 40°. There are a spread of Fe–Fe bond distances ranging from 2.48–2.65 Å.more » In the second Fe site, Fe is bonded in a single-bond geometry to four Fe and one C atom. Both Fe–Fe bond lengths are 2.73 Å. The Fe–C bond length is 1.86 Å. In the third Fe site, Fe is bonded in a 2-coordinate geometry to one Dy and thirteen Fe atoms. There are one shorter (2.38 Å) and three longer (2.69 Å) Fe–Fe bond lengths. In the fourth Fe site, Fe is bonded in a single-bond geometry to three Fe and one C atom. The Fe–C bond length is 1.92 Å. C is bonded to two Dy and four Fe atoms to form CDy2Fe4 octahedra that share corners with two equivalent FeDy2Fe10 cuboctahedra, corners with four equivalent CDy2Fe4 octahedra, and faces with four equivalent FeDy2Fe10 cuboctahedra. The corner-sharing octahedral tilt angles are 60°.« less
