Materials Data on CsMnSe2 by Materials Project
CsMnSe2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. Cs1+ is bonded in a body-centered cubic geometry to eight equivalent Se2- atoms. All Cs–Se bond lengths are 3.74 Å. Mn3+ is bonded to four equivalent Se2- atoms to form corner-sharing MnSe4 tetrahedra. All Mn–Se bond lengths are 2.44 Å. Se2- is bonded in a distorted bent 120 degrees geometry to four equivalent Cs1+ and two equivalent Mn3+ atoms.
