Materials Data on InBP2H5NO9 by Materials Project

Abstract

InBP2HO9NH4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two ammonium molecules and one InBP2HO9 framework. In the InBP2HO9 framework, In3+ is bonded to six O2- atoms to form InO6 octahedra that share a cornercorner with one BO4 tetrahedra and corners with five PO4 tetrahedra. There are a spread of In–O bond distances ranging from 2.16–2.22 Å. B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share a cornercorner with one InO6 octahedra and corners with three PO4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. There is one shorter (1.46 Å) and three longer (1.48 Å) B–O 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 two equivalent InO6 octahedra and corners with two equivalent BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 37–55°. There are a spread of P–O bond distances ranging from 1.53–1.56 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent InO6 octahedra and a cornercorner with one BO4 tetrahedra. The corner-sharing octahedra tilt angles range from 35–50°. There are a spread of P–O bond distances ranging from 1.52–1.59 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one In3+ and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one B3+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one B3+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one In3+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one B3+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one In3+, one B3+, and one H1+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one In3+ and one P5+ atom.
