Materials Data on NaV(PO4)2 by Materials Project
NaV(PO4)2 crystallizes in the tetragonal P4_2nm 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 2.38–2.82 Å. V5+ is bonded to five O2- atoms to form distorted VO5 trigonal bipyramids that share corners with four PO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.60–1.91 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.49–1.61 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one PO4 tetrahedra and corners with two equivalent VO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.48–1.64 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one V5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Na1+ and two equivalent P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Na1+, one V5+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one V5+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Na1+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Na1+ and one P5+ atom.
