Title: Materials Data on La12Fe2I17 by Materials Project

Abstract

La12Fe2I17 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are six inequivalent La sites. In the first La site, La is bonded to one Fe and five I atoms to form a mixture of edge and corner-sharing LaFeI5 octahedra. The corner-sharing octahedral tilt angles are 3°. The La–Fe bond length is 2.87 Å. There are a spread of La–I bond distances ranging from 3.20–3.44 Å. In the second La site, La is bonded to one Fe and five I atoms to form a mixture of edge and corner-sharing LaFeI5 octahedra. The corner-sharing octahedral tilt angles are 3°. The La–Fe bond length is 2.93 Å. There are a spread of La–I bond distances ranging from 3.28–3.43 Å. In the third La site, La is bonded to one Fe and five I atoms to form a mixture of edge and corner-sharing LaFeI5 octahedra. The corner-sharing octahedra tilt angles range from 0–7°. The La–Fe bond length is 3.03 Å. There are a spread of La–I bond distances ranging from 3.30–3.45 Å. In the fourth La site, La is bonded in a 6-coordinate geometry to one Fe and five I atoms. The La–Fe bond length is 2.47 Å. There aremore » a spread of La–I bond distances ranging from 3.26–3.67 Å. In the fifth La site, La is bonded in a 6-coordinate geometry to one Fe and five I atoms. The La–Fe bond length is 2.53 Å. There are a spread of La–I bond distances ranging from 3.30–3.72 Å. In the sixth La site, La is bonded to one Fe and five I atoms to form a mixture of edge and corner-sharing LaFeI5 octahedra. The corner-sharing octahedra tilt angles range from 3–7°. The La–Fe bond length is 2.92 Å. There are a spread of La–I bond distances ranging from 3.22–3.50 Å. Fe is bonded in an octahedral geometry to six La atoms. There are nine inequivalent I sites. In the first I site, I is bonded in a T-shaped geometry to three La atoms. In the second I site, I is bonded in a distorted rectangular see-saw-like geometry to four La atoms. In the third I site, I is bonded in a distorted T-shaped geometry to three La atoms. In the fourth I site, I is bonded in a distorted rectangular see-saw-like geometry to four La atoms. In the fifth I site, I is bonded in a distorted T-shaped geometry to three La atoms. In the sixth I site, I is bonded in a rectangular see-saw-like geometry to four La atoms. In the seventh I site, I is bonded in a rectangular see-saw-like geometry to four La atoms. In the eighth I site, I is bonded in a 3-coordinate geometry to three La atoms. In the ninth I site, I is bonded in a distorted rectangular see-saw-like geometry to four La atoms.« less
