Materials Data on Rb(IO3)3 by Materials Project

Abstract

Rb(O3I)3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Rb is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Rb–O bond distances ranging from 2.97–3.43 Å. There are nine inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to one Rb and one I atom. The O–I bond length is 1.83 Å. In the second O site, O is bonded in a 1-coordinate geometry to one Rb and two I atoms. There are one shorter (1.85 Å) and one longer (2.47 Å) O–I bond lengths. In the third O site, O is bonded in a distorted single-bond geometry to one Rb and two I atoms. There are one shorter (1.87 Å) and one longer (2.67 Å) O–I bond lengths. In the fourth O site, O is bonded in a 1-coordinate geometry to one Rb and two I atoms. There are one shorter (1.85 Å) and one longer (2.57 Å) O–I bond lengths. In the fifth O site, O is bonded in a single-bond geometry to one Rb and one I atom. The O–I bond length is 1.85 Å. In the sixth O site, O is bonded in a distorted single-bond geometry to one Rb and one I atom. The O–I bond length is 1.84 Å. In the seventh O site, O is bonded in a 1-coordinate geometry to one Rb and two I atoms. There are one shorter (1.86 Å) and one longer (2.61 Å) O–I bond lengths. In the eighth O site, O is bonded in a distorted bent 120 degrees geometry to one Rb and one I atom. The O–I bond length is 1.84 Å. In the ninth O site, O is bonded in a distorted bent 120 degrees geometry to one Rb and one I atom. The O–I bond length is 1.87 Å. There are three inequivalent I sites. In the first I site, I is bonded in a 3-coordinate geometry to four O atoms. In the second I site, I is bonded in a 3-coordinate geometry to three O atoms. In the third I site, I is bonded in a 6-coordinate geometry to six O atoms.
