Materials Data on Al2P3H9(CO3)3 by Materials Project
Al2(CH3PO3)3 crystallizes in the trigonal P31c space group. The structure is three-dimensional. there are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with six PCO3 tetrahedra. There is three shorter (1.89 Å) and three longer (1.91 Å) Al–O bond length. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with four PCO3 tetrahedra. All Al–O bond lengths are 1.75 Å. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded in a distorted tetrahedral geometry to one P5+ and three H1+ atoms. The C–P bond length is 1.80 Å. All C–H bond lengths are 1.10 Å. In the second C4- site, C4- is bonded in a distorted tetrahedral geometry to one P5+ and three H1+ atoms. The C–P bond length is 1.80 Å. All C–H bond lengths are 1.10 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one C4- and three O2- atoms to form PCO3 tetrahedra that share a cornercorner with one AlO6 octahedra and corners with two equivalent AlO4 tetrahedra. The corner-sharing octahedral tilt angles are 30°. There is one shorter (1.51 Å) and two longer (1.55 Å) P–O bond length. In the second P5+ site, P5+ is bonded to one C4- and three O2- atoms to form PCO3 tetrahedra that share a cornercorner with one AlO6 octahedra and corners with two equivalent AlO4 tetrahedra. The corner-sharing octahedral tilt angles are 17°. There is one shorter (1.50 Å) and two longer (1.55 Å) P–O bond length. There are six inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one C4- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one C4- 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 distorted linear geometry to one Al3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom.
