Title: Materials Data on LiSc(SiO3)2 by Materials Project

Abstract

LiScSi2O6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are two shorter (2.08 Å) and two longer (2.12 Å) Li–O bond lengths. Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with two equivalent ScO6 octahedra. There are a spread of Sc–O bond distances ranging from 2.02–2.27 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent ScO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 36–60°. There is one shorter (1.62 Å) and three longer (1.65 Å) Si–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Sc3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Sc3+, and one Si4+ atom.
