description: MgLa10Ti7O30 is Orthorhombic Perovskite-derived structured and crystallizes in the trigonal P3 space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six TiO6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are three shorter (2.05 Å) and three longer (2.08 Å) Mg–O bond lengths. There are ten inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.44–2.90 Å.
