Materials Data on LiPWO4F by Materials Project
Abstract
LiWPO4F crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Li1+ is bonded to four O2- and one F1- atom to form distorted LiO4F square pyramids that share corners with two equivalent WO4F2 octahedra, corners with two equivalent PO4 tetrahedra, edges with two equivalent WO4F2 octahedra, an edgeedge with one LiO4F square pyramid, and an edgeedge with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–56°. There are a spread of Li–O bond distances ranging from 2.08–2.19 Å. The Li–F bond length is 1.98 Å. There are two inequivalent W3+ sites. In the first W3+ site, W3+ is bonded to four O2- and two equivalent F1- atoms to form WO4F2 octahedra that share corners with two equivalent WO4F2 octahedra, corners with four equivalent PO4 tetrahedra, and edges with four equivalent LiO4F square pyramids. The corner-sharing octahedral tilt angles are 54°. There are two shorter (2.13 Å) and two longer (2.18 Å) W–O bond lengths. Both W–F bond lengths are 2.15 Å. In the second W3+ site, W3+ is bonded to four O2- and two equivalent F1- atoms to form WO4F2 octahedra that share corners with two equivalent WO4F2 octahedra, corners with four equivalent LiO4F square pyramids,more »

The corner-sharing octahedra tilt angles range from 30–58°. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one W3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one W3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one W3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li1+, one W3+, and one P5+ atom. F1- is bonded in a distorted trigonal planar geometry to one Li1+ and two W3+ atoms.},
