Materials Data on LiMn4(PO4)3 by Materials Project
LiMn4(PO4)3 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Li1+ is bonded to four equivalent O2- atoms to form distorted LiO4 tetrahedra that share corners with eight MnO6 octahedra and corners with four equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 79°. All Li–O bond lengths are 2.28 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with two equivalent LiO4 tetrahedra, corners with four PO4 tetrahedra, edges with two equivalent MnO6 octahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedral tilt angles are 64°. There are a spread of Mn–O bond distances ranging from 2.10–2.26 Å. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with two equivalent MnO6 octahedra, corners with two equivalent LiO4 tetrahedra, corners with six PO4 tetrahedra, and edges with two equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 64°. There are a spread of Mn–O bond distances ranging from 2.17–2.35 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four equivalent O2- atoms to form PO4 tetrahedra that share corners with eight MnO6 octahedra. The corner-sharing octahedra tilt angles range from 45–49°. All P–O bond lengths are 1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six MnO6 octahedra, corners with two equivalent LiO4 tetrahedra, and an edgeedge with one MnO6 octahedra. The corner-sharing octahedra tilt angles range from 42–47°. There is two shorter (1.55 Å) and two longer (1.58 Å) P–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Mn2+ and one P5+ atom. In the second O2- site, O2- is bonded to one Li1+, two Mn2+, and one P5+ atom to form a mixture of distorted corner and edge-sharing OLiMn2P tetrahedra. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two Mn2+ and one P5+ atom.
