Materials Data on RbSeO4 by Materials Project
RbSeO4 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.34 Å. In the second Rb site, Rb is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.54 Å. There are two inequivalent Se sites. In the first Se site, Se is bonded in a tetrahedral geometry to four O atoms. There is two shorter (1.66 Å) and two longer (1.72 Å) Se–O bond length. In the second Se site, Se is bonded in a tetrahedral geometry to four O atoms. There are a spread of Se–O bond distances ranging from 1.65–1.71 Å. There are six inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to three Rb and one Se atom. In the second O site, O is bonded in a distorted single-bond geometry to two Rb and one Se atom. In the third O site, O is bonded in a distorted single-bond geometry to two Rb and one Se atom. In the fourth O site, O is bonded in a 1-coordinate geometry to three Rb and one Se atom. In the fifth O site, O is bonded in a distorted single-bond geometry to two equivalent Rb and one Se atom. In the sixth O site, O is bonded in a 1-coordinate geometry to three equivalent Rb and one Se atom.
