Materials Data on LiMnBO4 by Materials Project

LiMnBO4 is Ilmenite-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with four equivalent MnO6 octahedra, corners with four equivalent BO4 tetrahedra, edges with two equivalent MnO6 octahedra, and an edgeedge with one BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–63°. There are a spread of Li–O bond distances ranging from 2.02–2.22 Å. Mn4+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with two equivalent BO4 tetrahedra, edges with two equivalent LiO6 octahedra, edges with two equivalent MnO6 octahedra, and edges with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 55–63°. There are a spread of Mn–O bond distances ranging from 1.91–1.99 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with two equivalent MnO6 octahedra, corners with four equivalent LiO6 octahedra, an edgeedge with one LiO6 octahedra, and edges with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–66°. There are a spread of B–O bond distances ranging from 1.46–1.61 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Mn4+, and one B3+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Mn4+, and one B3+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li1+, one Mn4+, and one B3+ atom.
