CoSe2 is trigonal omega-like structured and crystallizes in the cubic Fd-3m space group. Co(1) is bonded to six equivalent Se(1) atoms to form edge-sharing CoSe6 octahedra. Se(1) is bonded in a distorted T-shaped geometry to three equivalent Co(1) atoms.
CoSe2 is trigonal omega-like structured and crystallizes in the cubic Fd-3m space group. Co(1) is bonded to six equivalent Se(1) atoms to form edge-sharing CoSe6 octahedra. All Co(1)-Se(1) bond lengths are 2.36 Å. Se(1) is bonded in a distorted T-shaped geometry to three equivalent Co(1) atoms.
