Materials Data on MgAlO3 by Materials Project
MgAlO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mg is bonded to twelve equivalent O atoms to form MgO12 cuboctahedra that share corners with twelve equivalent MgO12 cuboctahedra, faces with six equivalent MgO12 cuboctahedra, and faces with eight equivalent AlO6 octahedra. All Mg–O bond lengths are 2.60 Å. Al is bonded to six equivalent O atoms to form AlO6 octahedra that share corners with six equivalent AlO6 octahedra and faces with eight equivalent MgO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Al–O bond lengths are 1.84 Å. O is bonded in a distorted linear geometry to four equivalent Mg and two equivalent Al atoms.
