Abstract

Ba2MgLa2Ti3O12 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six equivalent LaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, faces with three equivalent LaO12 cuboctahedra, a faceface with one MgO6 octahedra, and faces with seven TiO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.84–2.90 Å. Mg2+ is bonded to six equivalent O2- atoms to form MgO6 octahedra that share corners with six equivalent TiO6 octahedra, faces with two equivalent BaO12 cuboctahedra, and faces with six equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 3°. All Mg–O bond lengths are 2.05 Å. La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six equivalent LaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, faces with three equivalent LaO12 cuboctahedra, faces with three equivalent MgO6 octahedra, and faces with five TiO6 octahedra.
