Materials Data on Nb2(PO4)3 by Materials Project
Nb2P3O12 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Nb+4.50+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six equivalent PO4 tetrahedra. There are three shorter (2.01 Å) and three longer (2.03 Å) Nb–O bond lengths. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 24–26°. 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 bent 150 degrees geometry to one Nb+4.50+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Nb+4.50+ and one P5+ atom.
