Materials Data on RbInPHO5 by Materials Project
RbIn(OH)PO4 crystallizes in the tetragonal P4_32_12 space group. The structure is three-dimensional. Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.79–3.33 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with two equivalent InO6 octahedra and corners with four equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 60°. There are two shorter (2.16 Å) and four longer (2.19 Å) In–O bond lengths. In the second In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with two equivalent InO6 octahedra and corners with four equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 60°. There are a spread of In–O bond distances ranging from 2.17–2.21 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four InO6 octahedra. The corner-sharing octahedra tilt angles range from 37–54°. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one In3+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two In3+ and one H1+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Rb1+, one In3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Rb1+, one In3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Rb1+, one In3+, and one P5+ atom.
