Abstract

La2Fe14C crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 12-coordinate geometry to two equivalent La and sixteen Fe atoms. Both La–La bond lengths are 3.69 Å. There are a spread of La–Fe bond distances ranging from 3.03–3.25 Å. In the second La site, La is bonded in a 1-coordinate geometry to three La, sixteen Fe, and one C atom. The La–La bond length is 3.53 Å. There are a spread of La–Fe bond distances ranging from 3.04–3.39 Å. The La–C bond length is 2.90 Å. There are six inequivalent Fe sites. In the first Fe site, Fe is bonded in a 2-coordinate geometry to two La and twelve Fe atoms. There are a spread of Fe–Fe bond distances ranging from 2.62–2.82 Å. In the second Fe site, Fe is bonded to three La and nine Fe atoms to form a mixture of distorted edge, face, and corner-sharing FeLa3Fe9 cuboctahedra. There are a spread of Fe–Fe bond distances ranging from 2.40–2.56 Å. In the third Fe site, Fe is bonded in a single-bond geometry to two La, seven Fe, and one Cmore »« less
