Materials Data on Ti3CrSb2(PO4)6 by Materials Project
Ti3CrSb2(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are three inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.94 Å) and three longer (2.09 Å) Ti–O bond lengths. In the second Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There is three shorter (1.92 Å) and three longer (2.07 Å) Ti–O bond length. In the third Ti4+ site, Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.94 Å) and three longer (2.08 Å) Ti–O bond lengths. Cr6+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (1.98 Å) and three longer (2.09 Å) Cr–O bond lengths. There are two inequivalent Sb sites. In the first Sb site, Sb is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are three shorter (2.33 Å) and three longer (2.37 Å) Sb–O bond lengths. In the second Sb site, Sb is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are three shorter (2.34 Å) and three longer (2.41 Å) Sb–O bond lengths. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CrO6 octahedra and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 28–45°. There are a spread of P–O bond distances ranging from 1.50–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CrO6 octahedra and corners with three TiO6 octahedra. The corner-sharing octahedra tilt angles range from 27–45°. There is two shorter (1.53 Å) and two longer (1.56 Å) P–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Sb, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr6+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Sb, and one P5+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Cr6+, one Sb, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Ti4+, one Sb, and one P5+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti4+ and one P5+ atom.
