Materials Data on GdH(SeO4)2 by Materials Project
GdH(SeO4)2 crystallizes in the orthorhombic Pbca 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 2.31–2.79 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are two inequivalent Se6+ sites. In the first Se6+ site, Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.66–1.69 Å. In the second Se6+ site, Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Se–O bond distances ranging from 1.64–1.78 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Se6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Se6+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Gd3+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Gd3+ and one Se6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to one Gd3+ and one Se6+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to one Gd3+, one H1+, and one Se6+ atom.
