Materials Data on Sb2P3(HO3)3 by Materials Project
Sb2P3(HO3)3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Sb–O bond distances ranging from 2.03–2.24 Å. In the second Sb site, Sb is bonded to five O2- atoms to form distorted SbO5 square pyramids that share corners with five PHO3 tetrahedra. There are a spread of Sb–O bond distances ranging from 2.04–2.48 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent SbO5 square pyramids. The P–H bond length is 1.40 Å. There is two shorter (1.54 Å) and one longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share a cornercorner with one SbO5 square pyramid. The P–H bond length is 1.41 Å. There is two shorter (1.53 Å) and one longer (1.57 Å) P–O bond length. In the third P5+ site, P5+ is bonded to one H1+ and three O2- atoms to form distorted PHO3 tetrahedra that share corners with two equivalent SbO5 square pyramids. The P–H bond length is 1.41 Å. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one P5+ atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one P5+ atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one P5+ atom. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Sb and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Sb and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Sb and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to one Sb and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Sb and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sb and one P5+ atom.
