Materials Data on PrIClO13 by Materials Project

PrO7IO2ClO4 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of four oxygen molecules; four ClO4 clusters; and one PrO7I sheet oriented in the (0, 0, 1) direction. In each ClO4 cluster, there are four inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.47 Å. In the second O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.44 Å. In the third O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.46 Å. In the fourth O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.47 Å. Cl is bonded in a tetrahedral geometry to four O atoms. In the PrO7I sheet, Pr is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Pr–O bond distances ranging from 2.33–2.82 Å. There are seven inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two equivalent Pr and one I atom. The O–I bond length is 1.92 Å. In the second O site, O is bonded in a single-bond geometry to one I atom. The O–I bond length is 1.78 Å. In the third O site, O is bonded in a water-like geometry to two equivalent I atoms. There are one shorter (1.99 Å) and one longer (2.08 Å) O–I bond lengths. In the fourth O site, O is bonded in a distorted trigonal non-coplanar geometry to two equivalent Pr and one I atom. The O–I bond length is 1.93 Å. In the fifth O site, O is bonded in a trigonal non-coplanar geometry to two equivalent Pr and one I atom. The O–I bond length is 1.93 Å. In the sixth O site, O is bonded in a bent 120 degrees geometry to one Pr and one O atom. The O–O bond length is 1.23 Å. In the seventh O site, O is bonded in a single-bond geometry to one O atom. I is bonded to six O atoms to form distorted edge-sharing IO6 octahedra.
