Materials Data on RbMnSe2 by Materials Project
RbMnSe2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Rb1+ is bonded in a body-centered cubic geometry to eight equivalent Se2- atoms. All Rb–Se bond lengths are 3.58 Å. Mn3+ is bonded to four equivalent Se2- atoms to form corner-sharing MnSe4 tetrahedra. All Mn–Se bond lengths are 2.45 Å. Se2- is bonded in a distorted water-like geometry to four equivalent Rb1+ and two equivalent Mn3+ atoms.
