Title: Materials Data on Na9Sc(MoO4)6 by Materials Project

Abstract

Na9Sc(MoO4)6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.39–3.07 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.96 Å. In the third Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.35–2.57 Å. Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with six MoO4 tetrahedra. There are three shorter (2.11 Å) and three longer (2.12 Å) Sc–O bond lengths. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one ScO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of Mo–O bond distances ranging from 1.78–1.84 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra thatmore » share a cornercorner with one ScO6 octahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Mo–O bond distances ranging from 1.78–1.83 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Na1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to three Na1+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Sc3+, and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Sc3+, and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Na1+ and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Na1+ and one Mo6+ atom.« less
