Materials Data on AlP(H2O3)2 by Materials Project
AlPO4(H2O)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.88–1.98 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent AlO6 octahedra. The corner-sharing octahedra tilt angles range from 28–42°. There is two shorter (1.54 Å) and two longer (1.56 Å) P–O bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.67 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.64 Å) H–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Al3+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one Al3+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Al3+, one P5+, and one H1+ 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 distorted trigonal planar geometry to one Al3+, one P5+, and one H1+ atom.
