Title: Materials Data on Lu2Fe17C3 by Materials Project

Abstract

Lu2Fe17C3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Lu is bonded in a distorted trigonal planar geometry to four Fe and three equivalent C atoms. There are one shorter (3.08 Å) and three longer (3.30 Å) Lu–Fe bond lengths. All Lu–C bond lengths are 2.47 Å. There are four inequivalent Fe sites. In the first Fe site, Fe is bonded in a 2-coordinate geometry to one Lu and thirteen Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.40–2.71 Å. 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 2.44 Å. The Fe–C bond length is 1.85 Å. In the third Fe site, Fe is bonded in a single-bond geometry to three Fe and one C atom. Both Fe–Fe bond lengths are 2.46 Å. The Fe–C bond length is 1.91 Å. In the fourth Fe site, Fe is bonded to two equivalent Lu and ten Fe atoms to form distorted FeLu2Fe10 cuboctahedra that share corners with four equivalent FeLu2Fe10 cuboctahedra, corners with two equivalent CLu2Fe4 octahedra, faces with four equivalent FeLu2Fe10 cuboctahedra, and faces with four equivalent CLu2Fe4more » octahedra. The corner-sharing octahedral tilt angles are 44°. C is bonded to two equivalent Lu and four Fe atoms to form CLu2Fe4 octahedra that share corners with two equivalent FeLu2Fe10 cuboctahedra, corners with four equivalent CLu2Fe4 octahedra, and faces with four equivalent FeLu2Fe10 cuboctahedra. The corner-sharing octahedral tilt angles are 60°.« less
