Materials Data on Al2P3H12(NO4)3 by Materials Project
Al2P3H12(NO4)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Al3+ is bonded to five O2- atoms to form AlO5 trigonal bipyramids that share corners with five PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.79–1.93 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 three equivalent AlO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.54–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent AlO5 trigonal bipyramids. All P–O bond lengths are 1.55 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a tetrahedral geometry to four H1+ atoms. There is two shorter (1.02 Å) and two longer (1.06 Å) N–H bond length. In the second N3- site, N3- is bonded in a tetrahedral geometry to four H1+ atoms. There are a spread of N–H bond distances ranging from 1.03–1.06 Å. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- and one O2- atom. The H–O bond length is 1.70 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- and one O2- atom. The H–O bond length is 1.69 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Al3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one P5+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Al3+ and one P5+ atom.
