Materials Data on PrP3(HO2)6 by Materials Project

Abstract

PrP3(HO2)6 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. Pr3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are six shorter (2.52 Å) and three longer (2.60 Å) Pr–O bond lengths. P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.62 Å) P–O bond length. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent P5+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one Pr3+ and two equivalent H1+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Pr3+ and one P5+ atom.
