Materials Data on LiEu2CI3N2 by Materials Project
LiI3Eu2CN2 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional and consists of one Eu2CN2 framework and one LiI3 framework. In the Eu2CN2 framework, Eu2+ is bonded in a 3-coordinate geometry to three equivalent N3- atoms. All Eu–N bond lengths are 2.61 Å. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.24 Å. N3- is bonded in a 4-coordinate geometry to three equivalent Eu2+ and one C4+ atom. In the LiI3 framework, Li1+ is bonded to six equivalent I1- atoms to form corner-sharing LiI6 octahedra. The corner-sharing octahedral tilt angles are 46°. All Li–I bond lengths are 2.93 Å. I1- is bonded in a 4-coordinate geometry to two equivalent Li1+ atoms.
