Materials Data on YbI2 by Materials Project
YbI2 is trigonal omega structured and crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one YbI2 sheet oriented in the (0, 0, 1) direction. Yb2+ is bonded to six equivalent I1- atoms to form edge-sharing YbI6 octahedra. All Yb–I bond lengths are 3.15 Å. I1- is bonded in a distorted T-shaped geometry to three equivalent Yb2+ atoms.
