Materials Data on Li2UI6 by Materials Project
Li2UI6 is trigonal omega-derived structured and crystallizes in the trigonal P-31c space group. The structure is two-dimensional and consists of two Li2UI6 sheets oriented in the (0, 0, 1) direction. Li1+ is bonded to six equivalent I1- atoms to form LiI6 octahedra that share edges with three equivalent LiI6 octahedra and edges with three equivalent UI6 octahedra. All Li–I bond lengths are 3.04 Å. U4+ is bonded to six equivalent I1- atoms to form UI6 octahedra that share edges with six equivalent LiI6 octahedra. All U–I bond lengths are 3.02 Å. I1- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one U4+ atom.
