Materials Data on LiSi2BiO6 by Materials Project
LiSi2BiO6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are two shorter (1.95 Å) and two longer (2.07 Å) Li–O bond lengths. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent BiO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 42–66°. There are a spread of Si–O bond distances ranging from 1.63–1.67 Å. Bi3+ is bonded to six O2- atoms to form distorted BiO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with two equivalent BiO6 octahedra. There are a spread of Bi–O bond distances ranging from 2.22–2.64 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, one Si4+, and two equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Si4+, and one Bi3+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Si4+ atoms.
