Materials Data on RbLiS by Materials Project
RbLiS is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Rb1+ is bonded in a 5-coordinate geometry to five equivalent S2- atoms. There are four shorter (3.36 Å) and one longer (3.60 Å) Rb–S bond lengths. Li1+ is bonded to four equivalent S2- atoms to form a mixture of corner and edge-sharing LiS4 tetrahedra. All Li–S bond lengths are 2.56 Å. S2- is bonded in a 9-coordinate geometry to five equivalent Rb1+ and four equivalent Li1+ atoms.
