Materials Data on LiMnNbO4 by Materials Project
LiMnNbO4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with six equivalent NbO6 octahedra and corners with six equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 56–62°. There are two shorter (2.06 Å) and two longer (2.18 Å) Li–O bond lengths. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent NbO6 octahedra, and edges with four equivalent MnO6 octahedra. There are two shorter (1.98 Å) and four longer (2.07 Å) Nb–O bond lengths. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent MnO6 octahedra, and edges with four equivalent NbO6 octahedra. There are four shorter (2.16 Å) and two longer (2.31 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, one Nb5+, and two equivalent Mn2+ atoms. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Nb5+, and one Mn2+ atom.
