Materials Data on Tm2FeC4 by Materials Project
Tm2FeC4 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Tm3+ is bonded in a 7-coordinate geometry to seven C2- atoms. There are a spread of Tm–C bond distances ranging from 2.35–2.61 Å. Fe2+ is bonded to four equivalent C2- atoms to form distorted FeC4 trigonal pyramids that share corners with four equivalent CTm5C octahedra and edges with two equivalent FeC4 trigonal pyramids. The corner-sharing octahedral tilt angles are 42°. All Fe–C bond lengths are 1.91 Å. There are two inequivalent C2- sites. In the first C2- site, C2- is bonded in a 5-coordinate geometry to two equivalent Tm3+, two equivalent Fe2+, and one C2- atom. The C–C bond length is 1.38 Å. In the second C2- site, C2- is bonded to five equivalent Tm3+ and one C2- atom to form distorted CTm5C octahedra that share corners with six equivalent CTm5C octahedra, corners with two equivalent FeC4 trigonal pyramids, and edges with seven equivalent CTm5C octahedra. The corner-sharing octahedra tilt angles range from 7–54°.
