Materials Data on CsGaP3HO10 by Materials Project
CsGaP3HO10 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Cs1+ is bonded in a 2-coordinate geometry to ten O2- atoms. There are a spread of Cs–O bond distances ranging from 3.09–3.72 Å. Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.97–2.01 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 two equivalent GaO6 octahedra and a cornercorner with one PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 31–49°. There are a spread of P–O bond distances ranging from 1.51–1.66 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent GaO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. There is two shorter (1.51 Å) and two longer (1.60 Å) P–O bond length. H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.21 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Ga3+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+, one Ga3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Cs1+, one Ga3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cs1+ and two P5+ atoms.
