Materials Data on Na3Sc2(PO4)3 by Materials Project
Na3Sc2(PO4)3 is Esseneite-like structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.52–2.99 Å. Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.08 Å) and three longer (2.12 Å) Sc–O bond lengths. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent ScO6 octahedra. The corner-sharing octahedra tilt angles range from 28–30°. All P–O bond lengths are 1.55 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Na1+, one Sc3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Sc3+, and one P5+ atom.
