Materials Data on Mn3Cr2Sb(PO4)6 by Materials Project
Abstract
Cr2Mn3Sb(PO4)6 crystallizes in the trigonal R3 space group. The structure is three-dimensional. there are two inequivalent Cr+4.50+ sites. In the first Cr+4.50+ site, Cr+4.50+ is bonded to six O2- atoms to form distorted CrO6 octahedra that share corners with six PO4 tetrahedra, a faceface with one MnO6 octahedra, and a faceface with one SbO6 octahedra. There are three shorter (2.11 Å) and three longer (2.23 Å) Cr–O bond lengths. In the second Cr+4.50+ site, Cr+4.50+ is bonded to six O2- atoms to form distorted CrO6 octahedra that share corners with six PO4 tetrahedra, a faceface with one MnO6 octahedra, and a faceface with one MnO6 pentagonal pyramid. There are three shorter (2.09 Å) and three longer (2.10 Å) Cr–O bond lengths. There are three inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one CrO6 octahedra. There are three shorter (1.98 Å) and three longer (2.14 Å) Mn–O bond lengths. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 pentagonal pyramids that share corners with six PO4 tetrahedra and a facefacemore »

There are three shorter (2.06 Å) and three longer (2.24 Å) Mn–O bond lengths. In the third Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with six PO4 tetrahedra and a faceface with one CrO6 octahedra.

The corner-sharing octahedra tilt angles range from 28–51°. There are a spread of P–O bond distances ranging from 1.50–1.58 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one SbO6 octahedra, corners with two CrO6 octahedra, corners with two MnO6 octahedra, and a cornercorner with one MnO6 pentagonal pyramid. The corner-sharing octahedra tilt angles range from 33–55°. There are a spread of P–O bond distances ranging from 1.50–1.65 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Mn2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Cr+4.50+, one Mn2+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Sb3+ and one P5+ atom.
