Materials Data on CoSeS by Materials Project
CoSeS is pyrite-derived structured and crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Co4+ is bonded to three equivalent Se2- and three equivalent S2- atoms to form corner-sharing CoSe3S3 octahedra. The corner-sharing octahedral tilt angles are 63°. All Co–Se bond lengths are 2.40 Å. All Co–S bond lengths are 2.31 Å. Se2- is bonded in a 4-coordinate geometry to three equivalent Co4+ and one S2- atom. The Se–S bond length is 2.39 Å. S2- is bonded in a 4-coordinate geometry to three equivalent Co4+ and one Se2- atom.
