Materials Data on Ag3P6H12N3O19 by Materials Project
(Ag(PO3)2)6(NH4)6O2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional and consists of eighteen ammonium molecules, six water molecules, and one Ag(PO3)2 framework. In the Ag(PO3)2 framework, Ag+1.67+ is bonded to five O2- atoms to form distorted AgO5 trigonal bipyramids that share corners with five PO4 tetrahedra and an edgeedge with one AgO5 trigonal bipyramid. There are a spread of Ag–O bond distances ranging from 2.37–2.65 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 corners with two equivalent PO4 tetrahedra and corners with two equivalent AgO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent PO4 tetrahedra and corners with three equivalent AgO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ag+1.67+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Ag+1.67+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Ag+1.67+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Ag+1.67+ and one P5+ atom.
