Abstract

Li3MgTi8O16 is Spinel-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with twelve TiO6 octahedra. The corner-sharing octahedra tilt angles range from 59–62°. There are three shorter (2.03 Å) and one longer (2.09 Å) Li–O bond lengths. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent MgO6 octahedra and corners with nine TiO6 octahedra. The corner-sharing octahedra tilt angles range from 57–60°. There are three shorter (2.00 Å) and one longer (2.10 Å) Li–O bond lengths. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with twelve TiO6 octahedra. The corner-sharing octahedra tilt angles range from 57–60°. There is one shorter (1.97 Å) and three longer (2.01 Å) Li–O bond length. Mg2+ is bonded to six O2- atoms to form MgO6 octahedra that share corners with three equivalent LiO4 tetrahedra, corners with three equivalent TiO4 tetrahedra, and edges with six TiO6 octahedra.
