Materials Data on Cs2LiMnO4 by Materials Project

Abstract

Cs2LiMnO4 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Cs–O bond distances ranging from 3.13–3.22 Å. In the second Cs site, Cs is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Cs–O bond distances ranging from 3.12–3.21 Å. Li is bonded to four O atoms to form LiO4 tetrahedra that share corners with two equivalent MnO4 tetrahedra and an edgeedge with one MnO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.96–2.04 Å. Mn is bonded to four O atoms to form MnO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and an edgeedge with one LiO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 1.72–1.74 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted bent 150 degrees geometry to two Cs, one Li, and one Mn atom. In the second O site, O is bonded in a distorted L-shaped geometry to four Cs, one Li, and one Mn atom. In the third O site, O is bonded in a distorted L-shaped geometry to four Cs, one Li, and one Mn atom.
