Materials Data on La2ZnCrO6 by Materials Project
La2CrZnO6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. La3+ is bonded in a 3-coordinate geometry to nine equivalent O2- atoms. There are a spread of La–O bond distances ranging from 2.39–2.84 Å. Cr4+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent ZnO6 octahedra. The corner-sharing octahedral tilt angles are 25°. All Cr–O bond lengths are 1.95 Å. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent CrO6 octahedra. The corner-sharing octahedral tilt angles are 25°. All Zn–O bond lengths are 2.09 Å. O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Cr4+, and one Zn2+ atom.
