Materials Data on CoI2 by Materials Project
CoI2 is trigonal omega structured and crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one CoI2 sheet oriented in the (0, 0, 1) direction. Co2+ is bonded to six equivalent I1- atoms to form edge-sharing CoI6 octahedra. All Co–I bond lengths are 2.74 Å. I1- is bonded in a distorted T-shaped geometry to three equivalent Co2+ atoms.
