description: Li2CuP3H8O13 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 distorted LiO6 octahedra that share corners with four PO4 tetrahedra and edges with three LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.04–2.64 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with four PO4 tetrahedra and edges with three LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.15–2.57 Å. Cu1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.97–2.15 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four LiO6 octahedra and corners with two PO4 tetrahedra.
