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.
