Title: Materials Data on Co(RhSe2)2 by Materials Project

Abstract

Co(RhSe2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Rh3+ is bonded to six Se2- atoms to form RhSe6 octahedra that share corners with six equivalent CoSe6 octahedra, edges with six equivalent RhSe6 octahedra, and a faceface with one CoSe6 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. There are a spread of Rh–Se bond distances ranging from 2.47–2.60 Å. Co2+ is bonded to six Se2- atoms to form CoSe6 octahedra that share corners with twelve equivalent RhSe6 octahedra, edges with two equivalent CoSe6 octahedra, and faces with two equivalent RhSe6 octahedra. The corner-sharing octahedra tilt angles range from 49–54°. There are two shorter (2.47 Å) and four longer (2.50 Å) Co–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Rh3+ and one Co2+ atom. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to three equivalent Rh3+ and two equivalent Co2+ atoms.
