Materials Data on LiMn3P3(HO6)2 by Materials Project
LiMn3P3(HO6)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.09 Å) and two longer (2.38 Å) Li–O bond lengths. 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 six PO4 tetrahedra and edges with two MnO6 octahedra. There are a spread of Mn–O bond distances ranging from 2.16–2.28 Å. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent MnO6 octahedra. There are four shorter (2.21 Å) and two longer (2.33 Å) Mn–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six MnO6 octahedra. The corner-sharing octahedra tilt angles range from 37–57°. There are a spread of P–O bond distances ranging from 1.53–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six MnO6 octahedra. The corner-sharing octahedra tilt angles range from 54–57°. All P–O bond lengths are 1.56 Å. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.10 Å) and one longer (1.36 Å) H–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+, one Mn2+, and one P5+ atom to form a mixture of distorted edge and corner-sharing OLi2MnP tetrahedra. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Mn2+ and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Mn2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mn2+, one P5+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mn2+, one P5+, and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Mn2+ and one P5+ atom.
