Materials Data on LiMnPO4 by Materials Project
LiMnPO4 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.87–1.99 Å. In the second Li1+ site, Li1+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.01 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to four O2- atoms to form distorted MnO4 tetrahedra that share corners with two equivalent MnO4 tetrahedra, corners with four PO4 tetrahedra, and a cornercorner with one MnO4 trigonal pyramid. There are a spread of Mn–O bond distances ranging from 1.96–2.13 Å. In the second Mn2+ site, Mn2+ is bonded to four O2- atoms to form distorted MnO4 trigonal pyramids that share a cornercorner with one MnO4 tetrahedra and corners with four PO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.04–2.24 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one MnO4 tetrahedra and corners with two equivalent MnO4 trigonal pyramids. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent MnO4 tetrahedra and corners with two equivalent MnO4 trigonal pyramids. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Mn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Mn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Li1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Li1+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Mn2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Mn2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn2+, and one P5+ atom.
