Materials Data on GdH2I3O10 by Materials Project
Gd(IO3)3H2O crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional and consists of two water molecules and one Gd(IO3)3 framework. In the Gd(IO3)3 framework, Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.33–2.55 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.84 Å. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.84 Å. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.83 Å. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.84 Å. In the fifth O2- site, O2- is bonded in a single-bond geometry to one I5+ atom. The O–I bond length is 1.82 Å. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Gd3+ and two I5+ atoms. There are one shorter (1.86 Å) and one longer (2.65 Å) O–I bond lengths. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.82 Å. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.85 Å. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to one Gd3+ and one I5+ atom. The O–I bond length is 1.83 Å. There are three inequivalent I5+ sites. In the first I5+ site, I5+ is bonded in a 3-coordinate geometry to four O2- atoms. In the second I5+ site, I5+ is bonded in a 4-coordinate geometry to three O2- atoms. In the third I5+ site, I5+ is bonded in a 3-coordinate geometry to three O2- atoms.
