Materials Data on NaGe2(PO4)3 by Materials Project
Abstract
NaGe2P3O12 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Na1+ is bonded in a hexagonal planar geometry to six equivalent O2- atoms. All Na–O bond lengths are 2.43 Å. Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with six equivalent PO4 tetrahedra. There is three shorter (1.87 Å) and three longer (1.90 Å) Ge–O bond length. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent GeO6 octahedra. The corner-sharing octahedra tilt angles range from 30–35°. All P–O bond lengths are 1.54 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Ge4+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Ge4+ and one P5+ atom.
