LiMnPH2O5 crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent MnO4 tetrahedra and corners with four equivalent PO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.92–2.05 Å. Mn2+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with three equivalent LiO4 tetrahedra and corners with three equivalent PO4 tetrahedra. There are a spread of Mn–O bond distances ranging from 2.04–2.20 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent MnO4 tetrahedra and corners with four equivalent LiO4 tetrahedra. There is one shorter (1.52 Å) and three longer (1.57 Å) P–O bond length. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Mn2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Li1+ 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 trigonal planar geometry to one Li1+, one Mn2+, 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.
