Materials Data on Pr(ClO2)3 by Materials Project

Pr(O2Cl)3 crystallizes in the monoclinic P2/c space group. The structure is two-dimensional and consists of one Pr(O2Cl)3 sheet oriented in the (0, 1, 0) direction. Pr is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Pr–O bond distances ranging from 2.31–2.65 Å. There are three inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Pr and one Cl atom. The O–Cl bond length is 1.54 Å. In the second O site, O is bonded in a bent 120 degrees geometry to one Pr and one Cl atom. The O–Cl bond length is 1.65 Å. In the third O site, O is bonded in a bent 120 degrees geometry to one Pr and one O atom. The O–O bond length is 1.30 Å. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a single-bond geometry to one O atom. In the second Cl site, Cl is bonded in a water-like geometry to two equivalent O atoms.
