Materials Data on Rb2LiVS4 by Materials Project

Abstract

Rb2LiVS4 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are a spread of Rb–S bond distances ranging from 3.48–3.83 Å. Li1+ is bonded to four equivalent S2- atoms to form distorted LiS4 tetrahedra that share edges with two equivalent VS4 tetrahedra. All Li–S bond lengths are 2.43 Å. V5+ is bonded to four equivalent S2- atoms to form VS4 tetrahedra that share edges with two equivalent LiS4 tetrahedra. All V–S bond lengths are 2.16 Å. S2- is bonded in a 2-coordinate geometry to four equivalent Rb1+, one Li1+, and one V5+ atom.
