Title: Materials Data on Ce(SeO4)2 by Materials Project

Abstract

Ce(SeO4)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Ce4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.30–2.47 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 1.66–1.68 Å. In the second Se6+ site, Se6+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.66 Å) and three longer (1.67 Å) Se–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Ce4+ and one Se6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Ce4+ and one Se6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one Se6+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one Se6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometrymore » to one Ce4+ and one Se6+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one Se6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce4+ and one Se6+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce4+ and one Se6+ atom.« less
