Materials Data on InPH5NO5 by Materials Project
(NH4)In(OH)PO4 crystallizes in the tetragonal P4_32_12 space group. The structure is three-dimensional. 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 a spread of In–O bond distances ranging from 2.13–2.20 Å. 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 2.18–2.23 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 34–55°. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. N3- is bonded in a tetrahedral geometry to four H1+ atoms. There are a spread of N–H bond distances ranging from 1.03–1.05 Å. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third 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 fourth H1+ site, H1+ is bonded in a single-bond geometry to one N3- and one O2- atom. The H–O bond length is 1.75 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to 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 bent 150 degrees geometry to one In3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one In3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one In3+, one P5+, and one H1+ atom.
