description: LiMnP2HO7 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six PO4 tetrahedra and an edgeedge with one LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.13–2.33 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with six PO4 tetrahedra and an edgeedge with one LiO6 octahedra. There are a spread of Li–O bond distances ranging from 1.96–2.54 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Mn–O bond distances ranging from 2.09–2.42 Å. In the second Mn2+ site, Mn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 2.13–2.65 Å. There are four inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three LiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–58°. There are a spread of P–O bond distances ranging from 1.49–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three LiO6 octahedra and a cornercorner with one PO4 tetrahedra.

In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three LiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 46–54°. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three LiO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 40–61°. There are a spread of P–O bond distances ranging from 1.51–1.62 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted bent 150 degrees geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.55 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.55 Å) H–O bond length. There are fourteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Mn2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, two Mn2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Mn2+, one P5+, and one H1+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two P5+ atoms.

In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Mn2+, one P5+, and one H1+ atom. In the twelfth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one P5+, and one H1+ atom. In the thirteenth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one P5+ atom. In the fourteenth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Mn2+, and one P5+ atom.
