Abstract

Al3P2H10O13F3(H2O)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of four water molecules and one Al3P2H10O13F3 sheet oriented in the (0, 1, 0) direction. In the Al3P2H10O13F3 sheet, there are three inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to five O2- and one F1- atom to form AlO5F octahedra that share a cornercorner with one AlO4F2 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedral tilt angles are 35°. There are a spread of Al–O bond distances ranging from 1.84–2.01 Å. The Al–F bond length is 1.85 Å. In the second Al3+ site, Al3+ is bonded to four O2- and two F1- atoms to form AlO4F2 octahedra that share corners with two AlO5F octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 35–36°. There are a spread of Al–O bond distances ranging from 1.86–1.98 Å. There is one shorter (1.86 Å) and one longer (1.88 Å) Al–F bond length. In the third Al3+ site, Al3+ is bonded to four O2- and two F1- atoms to form AlO4F2 octahedra that share a cornercorner with one AlO4F2 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedral tilt angles are 36°. There are a spread of Al–O bond distances ranging from 1.83–1.93 Å. There is one shorter (1.85 Å) and one longer (1.87 Å) Al–F bond length. 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 four AlO5F octahedra. The corner-sharing octahedra tilt angles range from 40–46°. There are a spread of P–O bond distances ranging from 1.52–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four AlO5F octahedra. The corner-sharing octahedra tilt angles range from 36–49°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. There are ten 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 1.01 Å. In the third 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 fourth 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 fifth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.69 Å) H–O bond length. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the seventh 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 eighth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.65 Å) H–O bond length. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.71 Å) H–O bond length. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Al3+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 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 water-like geometry to one Al3+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one Al3+ and two H1+ atoms.
