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.

Materials Data on Rb2LiS2 by Materials Project

Rb2LiS2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Rb2LiS2 cluster. Rb1+ is bonded in a single-bond geometry to one S+1.50- atom. The Rb–S bond length is 2.91 Å. Li1+ is bonded in a linear geometry to two equivalent S+1.50- atoms. Both Li–S bond lengths are 2.30 Å. S+1.50- is bonded in a linear geometry to one Rb1+ and one Li1+ atom.
