Materials Data on La2MgWO6 by Materials Project
MgLa2WO6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Mg2+ is bonded to six equivalent O2- atoms to form MgO6 octahedra that share corners with six equivalent WO6 octahedra. The corner-sharing octahedral tilt angles are 28°. All Mg–O bond lengths are 2.08 Å. La3+ is bonded in a 3-coordinate geometry to nine equivalent O2- atoms. There are a spread of La–O bond distances ranging from 2.39–2.89 Å. W4+ is bonded to six equivalent O2- atoms to form WO6 octahedra that share corners with six equivalent MgO6 octahedra. The corner-sharing octahedral tilt angles are 28°. All W–O bond lengths are 2.07 Å. O2- is bonded in a 5-coordinate geometry to one Mg2+, three equivalent La3+, and one W4+ atom.
