Materials Data on ZnP3NO9 by Materials Project
(Zn(PO3)3)2N2 crystallizes in the hexagonal P-6c2 space group. The structure is three-dimensional and consists of two ammonia molecules and one Zn(PO3)3 framework. In the Zn(PO3)3 framework, Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent PO4 tetrahedra. All Zn–O bond lengths are 2.09 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent ZnO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 41°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Zn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent P5+ atoms.
