Title: Materials Data on La2MgTiO6 by Materials Project

Abstract

MgLa2TiO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with six equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 26–27°. All Mg–O bond lengths are 2.10 Å. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.40–2.81 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent MgO6 octahedra. The corner-sharing octahedra tilt angles range from 26–27°. There is four shorter (1.98 Å) and two longer (1.99 Å) Ti–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to one Mg2+, two equivalent La3+, and one Ti4+ atom to form distorted corner-sharing OLa2MgTi tetrahedra. In the second O2- site, O2- is bonded in a 5-coordinate geometry to one Mg2+, three equivalent La3+, and one Ti4+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to one Mg2+, three equivalent La3+, and one Ti4+ atom.
