description: Li4H(PO3)5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are four 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, edges with two equivalent LiO6 octahedra, an edgeedge with one LiO5 square pyramid, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.04–2.31 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share a cornercorner with one LiO4 tetrahedra, corners with five PO4 tetrahedra, edges with two LiO6 octahedra, and an edgeedge with one LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.00–2.39 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share a cornercorner with one LiO5 square pyramid, corners with four PO4 tetrahedra, an edgeedge with one LiO6 octahedra, and an edgeedge with one LiO5 square pyramid. There are a spread of Li–O bond distances ranging from 1.92–2.02 Å.

In the fifth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one LiO6 octahedra, a cornercorner with one LiO5 square pyramid, corners with two equivalent LiO4 tetrahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 41°. There is two shorter (1.50 Å) and two longer (1.62 Å) P–O bond length. H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.06 Å) and one longer (1.46 Å) H–O bond length. There are fifteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one P5+, and one H1+ atom.
