Materials Data on Rb(SeO3)2 by Materials Project

Abstract

Rb(SeO3)2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Rb is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Rb–O bond distances ranging from 2.95–3.31 Å. There are two inequivalent Se sites. In the first Se site, Se is bonded in a trigonal planar geometry to three O atoms. All Se–O bond lengths are 1.65 Å. In the second Se site, Se is bonded in a trigonal non-coplanar geometry to three O atoms. There is one shorter (1.66 Å) and two longer (1.67 Å) Se–O bond length. There are six inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to one Rb and one Se atom. In the second O site, O is bonded in a distorted single-bond geometry to one Rb and one Se atom. In the third O site, O is bonded in a distorted single-bond geometry to one Rb and one Se atom. In the fourth O site, O is bonded in a distorted single-bond geometry to one Rb and one Se atom. In the fifth O site, O is bonded in a 1-coordinate geometry to two equivalent Rb and one Se atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two equivalent Rb and one Se atom.
