Materials Data on Rb2MnSe2 by Materials Project
Rb2MnSe2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six equivalent Se2- atoms. There are a spread of Rb–Se bond distances ranging from 3.52–3.87 Å. Mn2+ is bonded to four equivalent Se2- atoms to form edge-sharing MnSe4 tetrahedra. All Mn–Se bond lengths are 2.58 Å. Se2- is bonded in a 2-coordinate geometry to six equivalent Rb1+ and two equivalent Mn2+ atoms.
