Materials Data on PrClO2 by Materials Project

PrO2Cl crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Pr is bonded in a 9-coordinate geometry to six O and three equivalent Cl atoms. There are a spread of Pr–O bond distances ranging from 2.40–2.54 Å. There are two shorter (2.93 Å) and one longer (2.98 Å) Pr–Cl bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a trigonal planar geometry to three equivalent Pr atoms. In the second O site, O is bonded in a trigonal planar geometry to three equivalent Pr atoms. Cl is bonded in a trigonal non-coplanar geometry to three equivalent Pr atoms.

Materials Data on PrClO2 by Materials Project

PrO2Cl crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Pr is bonded in a 9-coordinate geometry to six O and three equivalent Cl atoms. There are a spread of Pr–O bond distances ranging from 2.35–2.70 Å. There are two shorter (2.90 Å) and one longer (3.03 Å) Pr–Cl bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a 1-coordinate geometry to three equivalent Pr and two equivalent O atoms. Both O–O bond lengths are 1.95 Å. In the second O site, O is bonded in a trigonal non-coplanar geometry to three equivalent Pr atoms. Cl is bonded in a distorted trigonal non-coplanar geometry to three equivalent Pr atoms.
