Materials Data on GdP2H9O10 by Materials Project
GdP2H9O10 crystallizes in the orthorhombic Pnna space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Gd–O bond distances ranging from 2.36–2.46 Å. P5+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are five inequivalent H+0.78+ sites. In the first H+0.78+ site, H+0.78+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H+0.78+ site, H+0.78+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H+0.78+ site, H+0.78+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H+0.78+ site, H+0.78+ is bonded in a bent 150 degrees geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.21 Å. In the fifth H+0.78+ site, H+0.78+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to one Gd3+ and two H+0.78+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Gd3+ and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Gd3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to one Gd3+ and two H+0.78+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one P5+ and one H+0.78+ atom.
