Materials Data on Na3MoO4F by Materials Project
Abstract
Na3MoO4F crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four O2- and two equivalent F1- atoms to form distorted NaO4F2 octahedra that share corners with two equivalent NaO4F2 octahedra, corners with four equivalent NaO4F2 pentagonal pyramids, corners with four equivalent MoO4 tetrahedra, and faces with four equivalent NaO4F2 pentagonal pyramids. The corner-sharing octahedral tilt angles are 12°. There are a spread of Na–O bond distances ranging from 2.42–2.60 Å. There are one shorter (2.26 Å) and one longer (2.44 Å) Na–F bond lengths. In the second Na1+ site, Na1+ is bonded to four O2- and two equivalent F1- atoms to form distorted NaO4F2 pentagonal pyramids that share corners with two equivalent NaO4F2 octahedra, corners with three equivalent NaO4F2 pentagonal pyramids, corners with four equivalent MoO4 tetrahedra, edges with two equivalent NaO4F2 pentagonal pyramids, faces with two equivalent NaO4F2 octahedra, and a faceface with one NaO4F2 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 71–76°. There are a spread of Na–O bond distances ranging from 2.38–2.72 Å. There are one shorter (2.31 Å) and one longer (2.37 Å) Na–F bond lengths. Mo6+more »

In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Na1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Na1+ and one Mo6+ atom. In the third O2- site, O2- is bonded to three Na1+ and one Mo6+ atom to form ONa3Mo tetrahedra that share corners with six equivalent FNa6 octahedra.
