Materials Data on Rb2CoSe2 by Materials Project
Rb2CoSe2 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 3.51–3.68 Å. Co2+ is bonded to four equivalent Se2- atoms to form edge-sharing CoSe4 tetrahedra. All Co–Se bond lengths are 2.45 Å. Se2- is bonded in a 2-coordinate geometry to six equivalent Rb1+ and two equivalent Co2+ atoms.
