Abstract

La6Fe11Al3 crystallizes in the tetragonal I4cm space group. The structure is three-dimensional. there are four inequivalent La sites. In the first La site, La is bonded in a 6-coordinate geometry to one Fe and five Al atoms. The La–Fe bond length is 3.20 Å. There are a spread of La–Al bond distances ranging from 3.33–3.38 Å. In the second La site, La is bonded in a 6-coordinate geometry to four Fe and two equivalent Al atoms. There are a spread of La–Fe bond distances ranging from 3.04–3.37 Å. Both La–Al bond lengths are 3.41 Å. In the third La site, La is bonded in a 5-coordinate geometry to twelve Fe and one Al atom. There are a spread of La–Fe bond distances ranging from 3.08–3.30 Å. The La–Al bond length is 3.46 Å. In the fourth La site, La is bonded in a 5-coordinate geometry to eight Fe and five Al atoms. There are four shorter (3.12 Å) and four longer (3.24 Å) La–Fe bond lengths. There are four shorter (3.28 Å) and one longer (3.44 Å) La–Al bond lengths. There are five inequivalent Fe sites.
