Materials Data on RbAlBP2HO9 by Materials Project
RbAlBP2HO9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.96–3.26 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share a cornercorner with one BO4 tetrahedra and corners with five PO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.86–2.03 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share a cornercorner with one AlO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. There are a spread of B–O bond distances ranging from 1.47–1.50 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 AlO6 octahedra and a cornercorner with one BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 35–42°. There are a spread of P–O bond distances ranging from 1.53–1.60 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent AlO6 octahedra and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 42–49°. There are a spread of P–O bond distances ranging from 1.52–1.57 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Al3+, and one P5+ atom.
