Materials Data on CeP3H8O7 by Materials Project

CeP3H8O7 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one CeP3H8O7 sheet oriented in the (0, 1, -1) direction. Ce3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ce–O bond distances ranging from 2.43–2.66 Å. There are three inequivalent P+2.33+ sites. In the first P+2.33+ site, P+2.33+ is bonded in a distorted tetrahedral geometry to two H+0.50+ and two O2- atoms. Both P–H bond lengths are 1.42 Å. There is one shorter (1.52 Å) and one longer (1.53 Å) P–O bond length. In the second P+2.33+ site, P+2.33+ is bonded in a distorted tetrahedral geometry to two H+0.50+ and two O2- atoms. Both P–H bond lengths are 1.42 Å. Both P–O bond lengths are 1.53 Å. In the third P+2.33+ site, P+2.33+ is bonded in a distorted tetrahedral geometry to two H+0.50+ and two O2- atoms. Both P–H bond lengths are 1.42 Å. Both P–O bond lengths are 1.52 Å. There are eight inequivalent H+0.50+ sites. In the first H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one P+2.33+ atom. In the second H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one P+2.33+ atom. In the third H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one P+2.33+ atom. In the fourth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one P+2.33+ atom. In the fifth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one P+2.33+ atom. In the sixth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one P+2.33+ atom. In the seventh H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.70 Å) H–O bond length. In the eighth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Ce3+ and one P+2.33+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ce3+ and one P+2.33+ atom. In the third O2- site, O2- is bonded in a water-like geometry to one Ce3+ and two H+0.50+ atoms. In the fourth O2- site, O2- is bonded in a distorted linear geometry to one Ce3+ and one P+2.33+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ce3+ and one P+2.33+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ce3+, one P+2.33+, and one H+0.50+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Ce3+ and one P+2.33+ atom.

Materials Data on CeP2(HO4)2 by Materials Project

CeP2(HO3)2O2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is two-dimensional and consists of four hydrogen peroxide molecules and two CeP2(HO3)2 sheets oriented in the (0, 0, 1) direction. In each CeP2(HO3)2 sheet, Ce4+ is bonded to seven O2- atoms to form distorted CeO7 pentagonal bipyramids that share corners with five PHO3 tetrahedra, edges with two equivalent CeO7 pentagonal bipyramids, and an edgeedge with one PHO3 tetrahedra. There are a spread of Ce–O bond distances ranging from 2.16–2.57 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent CeO7 pentagonal bipyramids. The P–H bond length is 1.41 Å. There is one shorter (1.49 Å) and two longer (1.59 Å) P–O bond length. In the second P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with three equivalent CeO7 pentagonal bipyramids and an edgeedge with one CeO7 pentagonal bipyramid. The P–H bond length is 1.41 Å. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one P5+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one P5+ atom. There are six inequivalent O2- sites.
