Materials Data on Pr(ClO)3 by Materials Project

Abstract

PrOCl3O2 crystallizes in the orthorhombic Pnma space group. The structure is two-dimensional and consists of four hydrogen peroxide molecules and two PrOCl3 sheets oriented in the (0, 0, 1) direction. In each PrOCl3 sheet, Pr is bonded in a 6-coordinate geometry to two equivalent O and four equivalent Cl atoms. There are one shorter (2.34 Å) and one longer (2.40 Å) Pr–O bond lengths. There are two shorter (2.84 Å) and two longer (2.85 Å) Pr–Cl bond lengths. O is bonded in a trigonal planar geometry to two equivalent Pr and one Cl atom. The O–Cl bond length is 1.69 Å. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a water-like geometry to two equivalent Pr atoms. In the second Cl site, Cl is bonded in a single-bond geometry to one O atom.
