Materials Data on Li7NiN4 by Materials Project
Abstract
Li7NiN4 is alpha bismuth trifluoride-derived structured and crystallizes in the cubic P-43n space group. The structure is three-dimensional. there are five inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four N+2.50- atoms to form LiN4 tetrahedra that share corners with two equivalent NiN4 tetrahedra, corners with fourteen LiN4 tetrahedra, an edgeedge with one NiN4 tetrahedra, and edges with five LiN4 tetrahedra. There are two shorter (2.08 Å) and two longer (2.16 Å) Li–N bond lengths. In the second Li1+ site, Li1+ is bonded to four N+2.50- atoms to form LiN4 tetrahedra that share corners with two NiN4 tetrahedra, corners with fourteen LiN4 tetrahedra, an edgeedge with one NiN4 tetrahedra, and edges with five LiN4 tetrahedra. There are a spread of Li–N bond distances ranging from 2.05–2.20 Å. In the third Li1+ site, Li1+ is bonded to four N+2.50- atoms to form LiN4 tetrahedra that share corners with four NiN4 tetrahedra, corners with twelve LiN4 tetrahedra, and edges with six equivalent LiN4 tetrahedra. There are three shorter (2.14 Å) and one longer (2.20 Å) Li–N bond lengths. In the fourth Li1+ site, Li1+ is bonded to four equivalent N+2.50- atoms to form distorted LiN4 tetrahedra that sharemore »
