Materials Data on ThCr(IO5)2 by Materials Project
ThCr(O5I)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Th4+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Th–O bond distances ranging from 2.37–2.72 Å. Cr6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Cr–O bond distances ranging from 1.65–1.69 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Th4+ and one I5+ atom. The O–I bond length is 1.85 Å. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Th4+ and one I5+ atom. The O–I bond length is 1.82 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Th4+ and one I5+ atom. The O–I bond length is 1.83 Å. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Th4+ and one Cr6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Th4+ and one Cr6+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to one Cr6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Th4+ and one Cr6+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Th4+ and one I5+ atom. The O–I bond length is 1.82 Å. In the ninth O2- site, O2- is bonded in a 3-coordinate geometry to one Th4+ and two equivalent I5+ atoms. There are one shorter (1.86 Å) and one longer (2.60 Å) O–I bond lengths. In the tenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Th4+ and one I5+ atom. The O–I bond length is 1.83 Å. There are two inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 3-coordinate geometry to three O2- atoms. In the second I5+ site, I5+ is bonded in a 3-coordinate geometry to four O2- atoms.
