Materials Data on Li7IN2 by Materials Project
Li7N2I crystallizes in the cubic Fd-3m space group. The structure is three-dimensional and consists of eight lithium molecules and one Li6N2I framework. In the Li6N2I framework, Li1+ is bonded in a 2-coordinate geometry to two equivalent N3- and one I1- atom. Both Li–N bond lengths are 2.32 Å. The Li–I bond length is 2.63 Å. N3- is bonded in a distorted body-centered cubic geometry to six equivalent Li1+ and two equivalent I1- atoms. Both N–I bond lengths are 2.41 Å. I1- is bonded in a distorted q6 geometry to six equivalent Li1+ and four equivalent N3- atoms.
