Materials Data on Cs2ZrFe2(MoO4)6 by Materials Project
Cs2ZrFe2(MoO4)6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Cs1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Cs–O bond distances ranging from 3.31–3.74 Å. Zr4+ is bonded to six O2- atoms to form ZrO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of Zr–O bond distances ranging from 2.08–2.11 Å. There are three inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one ZrO6 octahedra and corners with two FeO6 octahedra. The corner-sharing octahedra tilt angles range from 13–38°. There are a spread of Mo–O bond distances ranging from 1.74–1.83 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one ZrO6 octahedra and corners with two FeO6 octahedra. The corner-sharing octahedra tilt angles range from 12–38°. There are a spread of Mo–O bond distances ranging from 1.74–1.83 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one ZrO6 octahedra and corners with two FeO6 octahedra. The corner-sharing octahedra tilt angles range from 12–39°. There are a spread of Mo–O bond distances ranging from 1.74–1.84 Å. There are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six MoO4 tetrahedra. There are two shorter (2.01 Å) and four longer (2.02 Å) Fe–O bond lengths. In the second Fe3+ site, Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of Fe–O bond distances ranging from 1.99–2.04 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cs1+, one Mo6+, and one Fe3+ atom.
