Materials Data on Li3Mn(BO3)2 by Materials Project

Abstract

Li3Mn(BO3)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.09 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent MnO5 square pyramids. There are a spread of Li–O bond distances ranging from 1.96–2.09 Å. In the third Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.90–2.26 Å. Mn3+ is bonded to five O2- atoms to form distorted MnO5 square pyramids that share corners with three equivalent LiO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 1.91–2.14 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.42 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.41 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Mn3+, and one B3+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mn3+, and one B3+ atom. In the third O2- site, O2- is bonded to three Li1+, one Mn3+, and one B3+ atom to form distorted edge-sharing OLi3MnB square pyramids. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Li1+, one Mn3+, and one B3+ atom. In the fifth O2- site, O2- is bonded in a 5-coordinate geometry to four Li1+ and one B3+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mn3+, and one B3+ atom.
