Materials Data on Na3Li(MoO7)2 by Materials Project

Abstract

Na3Li(MoO7)2 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are three inequivalent Na sites. In the first Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share a cornercorner with one LiO4 tetrahedra, corners with three MoO4 tetrahedra, and edges with two NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.35–2.58 Å. In the second Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share a cornercorner with one LiO4 tetrahedra, corners with three MoO4 tetrahedra, and edges with two NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.34–2.60 Å. In the third Na site, Na is bonded to six O atoms to form distorted NaO6 octahedra that share a cornercorner with one LiO4 tetrahedra, corners with three MoO4 tetrahedra, and edges with two NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.34–2.60 Å. Li is bonded to four O atoms to form distorted LiO4 tetrahedra that share corners with three NaO6 octahedra and a cornercorner with one MoO4 tetrahedra. The corner-sharing octahedra tilt angles range from 67–69°. There are a spread of Li–O bond distances ranging from 1.91–2.08 Å. There are two inequivalent Mo sites. In the first Mo site, Mo is bonded to four O atoms to form MoO4 tetrahedra that share corners with six NaO6 octahedra. The corner-sharing octahedra tilt angles range from 60–65°. There is two shorter (1.80 Å) and two longer (1.81 Å) Mo–O bond length. In the second Mo site, Mo is bonded to four O atoms to form MoO4 tetrahedra that share corners with three NaO6 octahedra and a cornercorner with one LiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 70–71°. There are a spread of Mo–O bond distances ranging from 1.74–1.83 Å. There are fourteen inequivalent O sites. In the first O site, O is bonded in a water-like geometry to one Na and one Mo atom. In the second O site, O is bonded in a water-like geometry to one Na and one Mo atom. In the third O site, O is bonded in a water-like geometry to one Na and one Mo atom. In the fourth O site, O is bonded in a linear geometry to one Li and one Mo atom. In the fifth O site, O is bonded in a distorted bent 120 degrees geometry to one Na and one Li atom. In the sixth O site, O is bonded in a water-like geometry to one Na and one Li atom. In the seventh O site, O is bonded in a distorted water-like geometry to one Na and one Li atom. In the eighth O site, O is bonded in a water-like geometry to two Na atoms. In the ninth O site, O is bonded in a water-like geometry to two Na atoms. In the tenth O site, O is bonded in a water-like geometry to two Na atoms. In the eleventh O site, O is bonded in a distorted tetrahedral geometry to three Na and one Mo atom. In the twelfth O site, O is bonded in a bent 120 degrees geometry to one Na and one Mo atom. In the thirteenth O site, O is bonded in a bent 120 degrees geometry to one Na and one Mo atom. In the fourteenth O site, O is bonded in a bent 120 degrees geometry to one Na and one Mo atom.
