Materials Data on RbLiSe by Materials Project
RbLiSe 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 Se2- atoms. There are four shorter (3.49 Å) and one longer (3.67 Å) Rb–Se bond lengths. Li1+ is bonded to four equivalent Se2- atoms to form a mixture of edge and corner-sharing LiSe4 tetrahedra. All Li–Se bond lengths are 2.69 Å. Se2- is bonded in a 9-coordinate geometry to five equivalent Rb1+ and four equivalent Li1+ atoms.
