Materials Data on RbLi2O3 by Materials Project

Abstract

RbLi2O3 crystallizes in the monoclinic P2_1/m space group. The structure is one-dimensional and consists of one RbLi2O3 ribbon oriented in the (0, 1, 0) direction. Rb is bonded in a 2-coordinate geometry to two O atoms. There are one shorter (2.88 Å) and one longer (2.93 Å) Rb–O bond lengths. Li is bonded in a 4-coordinate geometry to four O atoms. There are a spread of Li–O bond distances ranging from 1.89–1.94 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted rectangular see-saw-like geometry to four equivalent Li atoms. In the second O site, O is bonded in a 2-coordinate geometry to one Rb and two equivalent Li atoms. In the third O site, O is bonded in a distorted water-like geometry to one Rb and two equivalent Li atoms.
