Abstract

Er2Fe17C crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Er is bonded in a distorted single-bond geometry to fourteen Fe and one C atom. There are a spread of Er–Fe bond distances ranging from 2.99–3.31 Å. The Er–C bond length is 2.50 Å. There are seven inequivalent Fe sites. In the first Fe site, Fe is bonded in a 2-coordinate geometry to one Er and thirteen Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.39–2.76 Å. In the second Fe site, Fe is bonded in a single-bond geometry to seven Fe and one C atom. There are a spread of Fe–Fe bond distances ranging from 2.46–2.55 Å. The Fe–C bond length is 1.92 Å. In the third Fe site, Fe is bonded to three equivalent Er and nine Fe atoms to form FeEr3Fe9 cuboctahedra that share corners with twelve FeEr3Fe9 cuboctahedra, corners with two equivalent CEr2Fe4 octahedra, edges with six FeEr3Fe9 cuboctahedra, faces with seven FeEr3Fe9 cuboctahedra, and a faceface with one CEr2Fe4 octahedra. The corner-sharing octahedra tilt angles range from 65–70°. There are a spread of Fe–Fe bond distances ranging from 2.45–2.62 Å. In the fourth Fe site, Fe is bonded inmore »« less
