description: CuP4O11 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.98–2.45 Å. In the second Cu2+ site, Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.97–2.56 Å. There are eight inequivalent P5+ sites.
