Materials Data on La2ZnSnO6 by Materials Project
La2ZnSnO6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. La3+ is bonded in a distorted trigonal planar geometry to nine equivalent O2- atoms. There are a spread of La–O bond distances ranging from 2.37–2.93 Å. Zn2+ is bonded to six equivalent O2- atoms to form ZnO6 octahedra that share corners with six equivalent SnO6 octahedra. The corner-sharing octahedral tilt angles are 29°. All Zn–O bond lengths are 2.13 Å. Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with six equivalent ZnO6 octahedra. The corner-sharing octahedral tilt angles are 29°. All Sn–O bond lengths are 2.08 Å. O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Zn2+, and one Sn4+ atom.
