Materials Data on PrI3O10 by Materials Project
PrO10I3 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Pr is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Pr–O bond distances ranging from 2.44–2.61 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.86 Å. In the second O site, O is bonded in a bent 150 degrees geometry to one Pr and one I atom. The O–I bond length is 1.83 Å. In the third O site, O is bonded in a distorted bent 120 degrees geometry to one Pr and one I atom. The O–I bond length is 1.86 Å. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Pr and one I atom. The O–I bond length is 1.84 Å. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Pr and one I atom. The O–I bond length is 1.82 Å.
