Materials Data on Cr2(MoO4)3 by Materials Project
Cr2(MoO4)3 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. there are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with four equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 7–37°. There is three shorter (1.79 Å) and one longer (1.80 Å) Mo–O bond length. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with four equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 12–32°. There is two shorter (1.78 Å) and two longer (1.79 Å) Mo–O bond length. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six MoO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 1.99–2.01 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Mo6+ and one Cr3+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Cr3+ atom. In the third O2- site, O2- is bonded in a linear geometry to one Mo6+ and one Cr3+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Cr3+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Cr3+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo6+ and one Cr3+ atom.
