Materials Data on Li2Al2P2O9F by Materials Project
Abstract
Li2Al2P2O9F crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to five O atoms to form distorted LiO5 square pyramids that share corners with two equivalent AlO5F octahedra, corners with two PO4 tetrahedra, edges with two equivalent AlO5F octahedra, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 53–64°. There are a spread of Li–O bond distances ranging from 1.97–2.17 Å. In the second Li site, Li is bonded in a 5-coordinate geometry to four O and one F atom. There are a spread of Li–O bond distances ranging from 2.08–2.15 Å. The Li–F bond length is 1.98 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded to five O and one F atom to form AlO5F octahedra that share corners with two equivalent AlO5F octahedra, corners with four PO4 tetrahedra, and edges with two equivalent LiO5 square pyramids. The corner-sharing octahedra tilt angles range from 39–40°. There are a spread of Al–O bond distances ranging from 1.85–1.95 Å. The Al–F bond length is 1.89 Å. In the second Al site, Al ismore »
