Title: Materials Data on NaMn2FeAg(PO4)3 by Materials Project

Abstract

NaMn2FeAg(PO4)3 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.34–2.64 Å. There are three inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six PO4 tetrahedra, an edgeedge with one AgO8 hexagonal bipyramid, an edgeedge with one MnO6 octahedra, and an edgeedge with one FeO6 octahedra. There are a spread of Mn–O bond distances ranging from 2.08–2.31 Å. In the second Mn2+ site, Mn2+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with six PO4 tetrahedra, an edgeedge with one AgO8 hexagonal bipyramid, and edges with two equivalent MnO6 octahedra. There are two shorter (2.22 Å) and four longer (2.26 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 two equivalent AgO8 hexagonal bipyramids, corners with six PO4 tetrahedra, and edges with two equivalent FeO6 octahedra. There are a spread of Mn–O bond distances ranging from 2.21–2.32 Å. Fe3+ ismore » bonded to six O2- atoms to form FeO6 octahedra that share corners with six PO4 tetrahedra, an edgeedge with one AgO8 hexagonal bipyramid, and edges with two MnO6 octahedra.

In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent FeO6 octahedra, corners with four MnO6 octahedra, and an edgeedge with one AgO8 hexagonal bipyramid. The corner-sharing octahedra tilt angles range from 50–66°. There is two shorter (1.53 Å) and two longer (1.59 Å) P–O bond length. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent FeO6 octahedra, corners with four MnO6 octahedra, and an edgeedge with one AgO8 hexagonal bipyramid. The corner-sharing octahedra tilt angles range from 37–61°. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. In the fourth P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent FeO6 octahedra and corners with four MnO6 octahedra. The corner-sharing octahedra tilt angles range from 50–58°. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two Mn2+, one Ag1+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Fe3+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Fe3+, one Ag1+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+, one Mn2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Mn2+, two Ag1+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Mn2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Fe3+, one Ag1+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Mn2+, one Fe3+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Mn2+, one Ag1+, and one P5+ atom.
