Materials Data on Fe2Te4ClO12 by Materials Project
Fe2Te4O12Cl crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Fe+2.50+ is bonded to six O2- atoms to form edge-sharing FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.96–2.09 Å. There are two inequivalent Te5+ sites. In the first Te5+ site, Te5+ is bonded in a 3-coordinate geometry to three O2- and one Cl1- atom. There are a spread of Te–O bond distances ranging from 1.88–1.96 Å. The Te–Cl bond length is 3.11 Å. In the second Te5+ site, Te5+ is bonded in a distorted see-saw-like geometry to four O2- and one Cl1- atom. There are a spread of Te–O bond distances ranging from 1.86–2.02 Å. The Te–Cl bond length is 3.14 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two Te5+ and one Cl1- atom. The O–Cl bond length is 3.30 Å. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Fe+2.50+, one Te5+, and one Cl1- atom. The O–Cl bond length is 3.45 Å. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Te5+ and two equivalent Cl1- atoms. There are one shorter (3.18 Å) and one longer (3.35 Å) O–Cl bond lengths. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Fe+2.50+, one Te5+, and one Cl1- atom. The O–Cl bond length is 3.23 Å. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Fe+2.50+ and one Te5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Fe+2.50+ and one Te5+ atom. Cl1- is bonded in a 12-coordinate geometry to four Te5+ and ten O2- atoms.
