Materials Data on Li2La(NO3)5 by Materials Project
Li2La(NO3)5 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Li1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Li–O bond distances ranging from 2.11–2.71 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to twelve O2- atoms to form corner-sharing LaO12 cuboctahedra. There are a spread of La–O bond distances ranging from 2.67–2.71 Å. In the second La3+ site, La3+ is bonded to twelve O2- atoms to form corner-sharing LaO12 cuboctahedra. There are a spread of La–O bond distances ranging from 2.64–2.79 Å. There are four inequivalent N5+ sites. In the first N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.23 Å) and two longer (1.29 Å) N–O bond length. In the second N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.25 Å) and one longer (1.31 Å) N–O bond length. In the third N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of N–O bond distances ranging from 1.24–1.29 Å. In the fourth N5+ site, N5+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.26 Å) and two longer (1.27 Å) N–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one La3+, and one N5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one La3+ and one N5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, one La3+, and one N5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two La3+ and one N5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one La3+, and one N5+ atom. In the sixth O2- site, O2- is bonded in a single-bond geometry to two equivalent Li1+ and one N5+ atom. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to one Li1+, one La3+, and one N5+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one La3+ and one N5+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Li1+ and one N5+ atom. In the tenth O2- site, O2- is bonded in a T-shaped geometry to two equivalent Li1+ and one N5+ atom.
