Abstract

LiMnP3H8O13 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Li1+ is bonded to seven O2- atoms to form distorted LiO7 pentagonal bipyramids that share corners with five PO4 tetrahedra and edges with two MnO6 octahedra. There are a spread of Li–O bond distances ranging from 2.19–2.61 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 PO4 tetrahedra and edges with two equivalent LiO7 pentagonal bipyramids. There are two shorter (2.16 Å) and four longer (2.22 Å) Mn–O bond lengths. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with four PO4 tetrahedra and edges with two equivalent LiO7 pentagonal bipyramids.
