Materials Data on Nd(PO3)3 by Materials Project

Nd(PO3)3 crystallizes in the orthorhombic C222_1 space group. The structure is three-dimensional. Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.40–2.72 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.52 Å) and two longer (1.59 Å) P–O bond length. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nd3+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent P5+ atoms. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Nd3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted linear geometry to one Nd3+ and one P5+ atom.
