Materials Data on CeP2(NO4)2 by Materials Project

Ce(PO4)2N2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional and consists of eight ammonia molecules and one Ce(PO4)2 framework. In the Ce(PO4)2 framework, Ce4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.23–2.57 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.53 Å) and two longer (1.56 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Ce4+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Ce4+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one P5+ atom.

Materials Data on CeP4NO12 by Materials Project

(Ce(PO3)4)2N2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional and consists of four ammonia molecules and one Ce(PO3)4 framework. In the Ce(PO3)4 framework, Ce3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.33–2.43 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce3+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ce3+ and one P5+ atom.

Materials Data on CeP2N2O9 by Materials Project

(Ce(PO4)2)2(N2)2O2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional and consists of eight ammonia molecules, four water molecules, and one Ce(PO4)2 framework. In the Ce(PO4)2 framework, Ce4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.23–2.58 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.53 Å) and two longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ce4+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Ce4+ and one P5+ atom.
