Materials Data on AlPO4 by Materials Project
AlPO4 is Low Tridymite-derived structured and crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. there are three inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with two equivalent AlO4 tetrahedra and corners with two PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.69–1.83 Å. In the second Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra, corners with two PO4 tetrahedra, and a cornercorner with one AlO4 trigonal pyramid. There are a spread of Al–O bond distances ranging from 1.66–2.01 Å. In the third Al3+ site, Al3+ is bonded to four O2- atoms to form AlO4 trigonal pyramids that share a cornercorner with one AlO4 tetrahedra, a cornercorner with one PO4 tetrahedra, and corners with two equivalent AlO4 trigonal pyramids. There are a spread of Al–O bond distances ranging from 1.70–1.91 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra and corners with three PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.47–1.60 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra, corners with two PO4 tetrahedra, and a cornercorner with one AlO4 trigonal pyramid. There are a spread of P–O bond distances ranging from 1.46–1.68 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two AlO4 tetrahedra and corners with two equivalent PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.60 Å. There are seventeen 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 two equivalent P5+ atoms. 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 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 two P5+ atoms. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent P5+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Al3+ atoms. In the ninth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Al3+ atoms. In the tenth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent P5+ atoms. In the twelfth O2- site, O2- is bonded in a bent 150 degrees geometry to one Al3+ and one P5+ atom. In the thirteenth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent P5+ atoms. In the fourteenth O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Al3+ atoms. In the fifteenth O2- site, O2- is bonded in a bent 150 degrees geometry to two Al3+ atoms. In the sixteenth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Al3+ atoms. In the seventeenth O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Al3+ atoms.
